     DETAILED DESCRIPTION 
     Exemplary embodiments of this disclosure are described below and illustrated in the accompanying figures, in which like numerals refer to like parts throughout the several views. The embodiments described provide examples and should not be interpreted as limiting the scope of the invention. Other embodiments, and modifications and improvements of the described embodiments, will occur to those skilled in the art and all such other embodiments, modifications and improvements are within the scope of the present invention. 
     The present disclosure is directed to a rigid, portable, mobile structure including a framing system and tensioning system for use as a dwelling, storage facility or general purpose building. Although disclosed primarily within the context of a rigid, portable structure including a framing system and tensioning system, the skilled artisan will recognize that the principles of the present disclosure are not so limited but extend to any type of portable structure that includes a framing system and tensioning system that is lightweight and may be assembled rapidly. 
     For clarity of discussion, the following three directional definitions are commonly used when discussing structures and are used throughout this application. “Longitudinal” refers to a longitudinal axis “α” oriented in a direction parallel to a first side of a structure. “Lateral” refers to a direction orthogonal to the longitudinal direction and to a lateral axis “β” oriented in a direction parallel to a second side of the structure. “Vertical” refers to a vertical axis “δ” oriented in a direction orthogonal to the longitudinal direction and the lateral direction. Collectively, the three directional axes establish a Cartesian coordinate system. The Cartesian coordinate disclosed is consistent throughout the disclosure. For purposes of the present disclosure, the longitudinal direction a generally refers to a long side of the structure and the lateral direction β generally refers to a short side of the structure. (See for example the “directional vane” adjacent  FIG. 1  of the drawings. In some configurations, such as square shaped structures, the longitudinal direction α and lateral direction β may be interchangeable. In fact, in any of the configurations or embodiments disclosed herein, the longitudinal and lateral directions α, β may be interchangeable. From time-to-time in this description, longitudinally extending walls or framing components shall be referenced as “front” and “back” solely for the purposes of ease of description. The nomenclature is not meant to be limiting to the invention, but is meant to facilitate discussion and explanation of the structure of the disclosure. 
     A static compression structure according to the present disclosure comprises a series of rigid panels releasably held together, at least in part, by compressive forces applied to said rigid panels by a tensioning system. According to certain embodiments, the series of rigid panels are supported by a framing system such that the panels are placed into compression by a tensioning system associated with the framing system. The structure may be formed when rigid panels are brought together with the framing system. According to certain embodiments, the framing system may generally be comprised of a plurality of panel engaging cap members cooperatively interconnecting at corner connections and co-linear member connections and a plurality of tensioning members cooperating with the cap members. According to at least one embodiment, opposing cap members engage opposing edges of at least one rigid panel, tensioning members span the distance between opposing cap members and, while being placed in tension, compress the therebetween engaged panel. When fully assembled, wall, roof and floor panels are captured in the framing by compressive forces applied along at least two axes, for example, the lateral β and vertical δ directions. 
     With reference now to the drawings, in which like numerals represent like components throughout the several views, a static compression structure according to one aspect of the present disclosure is a portable modular structure  10  that may comprise (with reference to  FIGS. 1 ,  2   b ,  17  and  18 ) a pair of opposing side wall assemblies  7   a, b,  a pair of opposing end wall assemblies  8   a, b,  a roof assembly  9   a  and a floor assembly  9   b.  Since the structure  10  is modular, a plurality of side wall assemblies  7   a, b,  end wall assemblies  8   a, b,  roof assemblies  9   a  and floor assemblies  9   b  may be assembled to form a structure  10  that may have a variety of shapes and sizes (see  FIGS. 15   a - 15   h ). For example, whereas  FIGS. 1 and 2   b  illustrate aspects of a relatively large modular structure  10  of a first embodiment,  FIGS. 17 and 18  illustrate aspects of a relatively small modular structure of an alternate embodiment. 
     Doors  28  and windows may be formed in any wall assembly of the structure  10 . An example orientation of the components of the embodiment of  FIG. 1 , applying the directional definitions state above, may be as follows: the side wall assemblies  7   a,    7   b  extend in the longitudinal direction α and are spaced part in the lateral direction β; the end wall assemblies  8   a,    8   b  extend in the lateral direction β and are spaced apart in the longitudinal direction α; and the roof assembly  9   a  and floor assembly  9   b  are spaced apart in the vertical direction δ. Respective assemblies  7   a,    7   b,    8   a,    8   b ,  9   a,    9   b  may be connected at edges of the structure  10  to form outer corners of the structure  10 . For example, side wall assembly  7   a  may be connected with roof assembly  9   a  to form an outer corner of the structure  10 , and side wall assembly  7   a  may be connected with end wall assembly  8   a  to form an outer corner of the structure  10 . The structure  10  may be supported by a plurality of leveling bases  11 . It is anticipated that each leveling base  11  will be adjustable such that the structure  10  can be positioned on a foundation or base, or uneven ground, and have a level floor. 
     Each side wall assembly  7   a,    7   b  may be comprised of at least one wall panel  12 , a lower cap member  14  and an upper cap member  16 . The lower cap member  14  may engage with a lower edge of the wall panel  12  and the upper cap member  16  may engage with an upper edge of the wall panel  12  to support the wall panel  12  and form a portion of a framing system  5 . Furthermore, according to some embodiments, the lower and upper cap members  14 ,  16  are interchangeable with one another. The lower and upper cap members  14 ,  16  should be of sufficient length to span the length of at least one wall panel  12 , preferably of a length to span at least two wall panels, and most preferably of a length to span three or more panels. 
     Each end wall assembly  8   a,    8   b  may be comprised of at least one wall panel  12 , a lower cap member  14 ′ and an upper cap member  16 ′. The lower cap member  14 ′ may engage with a lower edge of the wall panel  12  and the upper cap member  16 ′ may engage with an upper edge of the wall panel  12  to support the wall panel  12  and form a portion of a framing system  5 . Furthermore, according to some embodiments, the lower and upper cap members  14 ′,  16 ′ are interchangeable with one another. The lower and upper cap members  14 ′,  16 ′ should be of sufficient length to span the length of at least one wall panel  12 , preferably of a length to span at least two wall panels, and most preferably of a length to span three or more panels. 
     Each roof assembly  9   a  may be comprised of at least one roof panel  13   a,  a front cap member  15  and a rear cap member  17 . The front cap member  15  may engage with a first edge of the roof panel  13   a  and the rear cap member  17  may engage with a second edge of the roof panel  13   a  to support the roof panel  13   a  and form a portion of a framing system  5 . Furthermore, according to some embodiments, the front and rear cap members  15 ,  17  are interchangeable with one another. The front and rear cap members  15 ,  17  should be of sufficient length to span the length of at least one roof panel  13   a  , preferably of a length to span at least two panels, and most preferably of a length to span three or more panels. 
     Each floor assembly  9   b  may be comprised of at least one floor panel  13   b,  a front cap member  15 ′ and a rear cap member  17 ′. The front cap member  15 ′ may engage with a first edge of the floor panel  13   b  and the rear channel  17 ′ may engage with a second edge of the floor panel  13   b  to support the floor panel  13   b  and form a portion of a framing system  5 . Furthermore, according to some embodiments, the front and rear cap members  15 ′,  17 ′ may be interchangeable with one another. The front and rear cap members  15 ′,  17 ′ should be of sufficient length to span the length of at least one floor panel  13   b,  preferably of a length to span at least two panels, and most preferably of a length to span three or more panels. 
     The structure  10  may comprise a plurality of vertically extending corner posts  19  arranged at corners of the structure  10 . Alternatively, some embodiments may require no end post at intersecting wall assemblies  7   a,    7   b,    8   a,    8   b  but may use a flashing or similar sheet metal material to conceal the intersection and offer some insulation benefits. A flashing or similar sheet metal material may offer the benefit of being able to form an intersection between a side wall element  7  and an end wall element  8  that is a non-perpendicular intersection. 
     Cap members  14 ,  15 ,  16 ,  17 ,  14 ′,  15 ′,  16 ′,  17 ′ are acceptably of a variety of configurations, so long as the configuration provides for at least the function of cooperating with a panel edge to accomplish the application of compression forces and so long as the configuration can cooperate with the tensioning members and the panel to effect the necessary forces, connections and stability that will be evident to one of skill in the art reading this disclosure. For example, but without limitation, the cap member may be a flat plate with acceptable panel gripping features and interfacing for the tensioning system. According to some embodiments, including those depicted in the appended drawings, each cap member is of a configuration having an elongated base plate and opposing, upstanding side plates, such that there is defined thereby an elongated, open channel or trough along the length of the cap member. This cap member configuration, which shall be referred to herein as a channel member, provides certain advantages to the current static compression structure that make the channel member more preferable than, for example, a flat plate without upstanding side plates (which, as mentioned above may be an acceptable but less preferred cap member). For example, but without limitation, the trough/channel of the channel member may engage with or accept therein an end portion of a panel  12 ,  13  (as opposed to simply engaging the edge of the panel). The trough of the channel member may have right-angled inner corners or may have a variety of other cross sectional shapes, including but not limited to, U-shaped, C-shaped, V-shaped, to accommodate the desired shape of the end portion of the respective panel. 
     According to at least one embodiment of the present disclosure, all of the channel members (lower  14 ,  14 ′, upper  16 ,  16 ′, front  15 ,  15 ′, and rear  17 ,  17 ′) are formed in a particular design referred to sometimes herein as a “double capture frame member” or a “double channel configuration”.  FIGS. 19   a - 19   l  illustrate but some of the possible cross section configurations for the double capture frame members. Double capture frame members may extend in the longitudinal direction α, the lateral direction β, or the vertical direction δ. For discussion purposes only, double capture frame members extending in the longitudinal direction α will have reference number  51  or  51 ′, double capture frame members extending in the lateral direction β will have reference number  53  or  53 ′ and double capture frame members extending in the vertical direction δ will have reference number  55 . For ease of description, the double capture frame members  51  intended for orientation in the longitudinally extending directions shall be referred to as “longitudinal frame members  51 ” and the double capture frame members  53  intended for orientation in the laterally extending directions shall be referred to as “lateral frame members  53 .”Double capture frame members support one edge of each of two adjacent perpendicular panels, such as, for example, a floor panel and a wall panel or a roof panel and a wall panel. The channel members  14 ,  15 ,  16 ,  17  may be arranged substantially orthogonal to one another when joined to form the respective double capture frame member. An example of one embodiment of a longitudinally extending double capture frame member  51  is seen by reference to  FIG. 3   a  as having an upper channel member  16  permanently attached to a rear channel member  17 , with their elongated, open channels/troughs oriented longitudinally parallel but facing at about 90 degrees to one another. It will be understood that, according to some embodiments of the present disclosure, each longitudinally extending double frame member  51  can be interchangeably used for a frame member  51  at any of the four longitudinal edges of the structure  10 ; for example each longitudinal double capture frame member  51  may function as any of an upper-front, upper-rear, lower-front and lower-rear frame member. Similarly, it will be understood that, according to some embodiments of the present disclosure, each laterally extending double frame member  53 ,  53 ′ can be interchangeably used for a frame member  53 ,  53 ′ at any of the four lateral edges of the structure  10 ; for example each lateral double capture frame member  53  may function as any of an upper-left, upper-right, lower-left and lower-right frame member. According to some embodiments, the floor panels  13   b  may be thicker than the wall panels  12  and thicker than the roof panels  13   a,  and, therefore, the upper frame members  51 ,  53  may not be interchangeable with a lower frame member  51 ′,  53 ′. For example, the trough opening of the channel member  15 ′,  17 ′ receiving the end section of a floor panel  13   b  may be wider than that of the channel member  15 ,  17  receiving either a wall panel  12  or a roof panel  13   a.  In such an embodiment, while the lower longitudinal frame member  51 ′ may still be used on either side of the floor panel  13   b,  it may not be useful as an upper frame member  51  supporting a roof panel  13   a.  The same would be true of lateral frame members  53 ′ in such an embodiment. For an example of a laterally extending double capture frame member  53 , refer inter alia to  FIG. 2   a . It is not required that the double capture frame member have two channel members arranged with their channel openings directed substantially perpendicular to one another, and the channel members may be arranged at any angle relative to each other to form non-parallelepiped structures. Further, alternatively, channel members forming a double capture frame member may be arranged non-parallel along their length to facilitate assembly, for example, of pitched or gabled roofs. See for example  FIGS. 5-14  discussed below. Similarly, the corner post  19  may also be configured as a double capture frame member  55  having channel members arranged to be substantially perpendicular and receive intersecting wall panels  12  at a corner of the structure  1 . Alternatively, the channel members forming a double capture corner post frame members  55  may be arranged at an angle relative to one another to facilitate non-perpendicular wall arrangements. 
     According to some embodiments, as herein depicted, all of the channel members and double capture members are substantially rigid or semi-rigid (for example sufficiently rigid to support its own weight across an intended span without substantial sagging) and may be fabricated from a lightweight metal, such as, for example, aluminum or a steel alloy. Alternatively, the channels and double capture members may be made of a heavy durable plastic, such as, for example, polyvinylchloride. All of the panels (wall, roof and floor) may be made of lightweight material and may have a composite structure. For example, an interior of the panels may be fabricated from a lightweight material such as foam and the exterior fabricated from a stronger material such as sheet metal. 
     A tensioning system  20  may be employed to place wall assemblies  7   a,    7   b,    8   a ,  8   b,  roof assemblies  9   a  and floor assemblies  9   b  into a compressed state. The tensioning system of the depicted embodiment may be comprised of a plurality of tensioning members  22 ,  26  and associated hooks or anchors (as discussed below). Lateral tensioning members  22  extend generally in the lateral direction β and vertical tensioning members  26  extend generally in the vertical direction δ. The tensioning members  22 ,  26  may be rigid or non-rigid depending on the particular application. Preferably, the tensioning members  22 ,  26  may be non-rigid. The tensioning members  22 ,  26  are also adjustable in length. As such, the tension associated with each tensioning member  22 ,  26  may be adjusted. A substantial portion of the tension in the tensioning member  22 ,  26  may be directly transferred to a respective wall assembly  7   a,    7   b,    8   a,    8   b,  roof assembly  9   a  or floor assembly  9   b  to place the particular assembly  7   a,    7   b,    8   a,    8   b,    9   a,    9   b  in a state of compression. The panels  12 ,  13   a ,  13   b  react to being placed in compression to become a stronger and more rigid panel. The tensioning system  20  may further comprise a plurality of stabilizing cables  24  that extend from the structure  10  to locations exterior the structure  10  to further anchor the structure  10  in position. The stabilizing cables  24  may also be adjustable and when installed, may be in tension. The stabilizing cables  24  may also apply additional compressive loading to the assemblies  7   a,    7   b,    8   a,    8   b,    9   a,    9   b.  Examples, without limitation, of acceptable tensioning members include (i) a heavy-duty nylon strap with connecting hooks at two displaced locations on the strap and with mechanical ratcheting mechanisms that (releasably) cinch the strap to shorten the distance between the two hooks and (ii) a cabling system including two cables, each with a connecting hook or eye-loop at one end, joined at their non-hooked ends by a cable cinching mechanism (such as a turnbuckle) that (releasably) draws the two cables toward one another to shorten the distance between the two hooks. 
       FIG. 2   a  is an exploded isometric view of a framing system  5  for the modular portable structure  10  according to the depicted embodiments of  FIGS. 1-4 . The framing system  5  may be comprised of longitudinal frame members, lateral frame members, corner brackets, in-line brackets, and corner posts  19  (if required by the particular embodiment). Since the structure  10  is modular, the framing system  5  is modular as well. In fact, the modular nature of the framing system  5  enhances the modular nature of the structure  10 . The longitudinal frame members  51  may have a connection element  34  at each end (see  FIG. 4   a ). The connection elements  34  of the longitudinal frame member  51  may extend from an outer surface of the double capture frame member  51  and perpendicular to the outer surface (as illustrated and for this particular embodiment, in the lateral direction β). The connection element  34  may facilitate connection of adjacent longitudinal frame members  51  with the tensioning system  20  (see  FIG. 4   a ). Similarly, according to the depicted embodiment of  FIG. 2   a , the lateral frame member  53  may have a connection element  34  at one end, also extending from an outer surface and generally perpendicular to the outer surface (as illustrated and for this particular embodiment, in the longitudinal direction α). The lateral frame member  53  of the depicted embodiment of  FIG. 2   a , has a connection element  34  at one end and an elongate connection element  36  at the other end (see  FIG. 3   a ). The elongate connection element  36  may be used at a corner assembly of the frame and may extend from the end of the lateral frame member  53  and in a direction parallel with the channel (as illustrated, in the lateral direction β). In some embodiments, it is anticipated that the double lateral frame member  53  may have an elongate connection element  36  at both ends. The connection element  34  and elongate connection element  36  may facilitate connection of the lateral frame member  53  with the tensioning system  20 . 
       FIGS. 3   a  and  3   b  are an exploded isometric view of a corner assembly and an isometric view of an assembled corner assembly, respectively, of the framing system  5  of  FIG. 2   a .  FIG. 3   b  shows elements of the tensioning system  20  at the corner assembly. A typical upper corner assembly may include a corner post  19 , a longitudinal frame member  51 , a lateral frame member  53 , a corner bracket  32 , and tensioning members  22 ,  26 . When the upper corner assembly is assembled, the longitudinal frame member  51  and the lateral frame member  53  may engage with an upper end of the corner post  19 . Similarly, when the lower corner assembly is assembled, the longitudinal frame member  51  and the lateral frame member  53  may engage with a lower end of the corner post  19 . With reference to a corner assembly only, the longitudinal frame member  51  may have a connection element  34  at the frame member end forming a portion of the corner assembly and the lateral frame member  53  may have an elongate connection element  36  at the frame member end that forms a portion of the corner assembly. The corner bracket  32  includes a slot  33  (see  FIG. 3   a ) formed therein and into which are received, side-by-side, the elongated connection element  36  and the connection element  34  of abutting, perpendicular frame members  51 ,  53 . Alternate embodiments may have multiple parallel slots in the single corner bracket  32 . In its manner of assembly, the combination of corner bracket  32  and two connection elements  34 ,  36  perform at least the dual function of connecting frame members  51 ,  53  and anchoring tensioning members  22 ,  26 . The connection element  34  may be formed with a hook shaped or “J” shaped anchor end  34 ′ and is intended to interact or engage with the tensioning members  26  by providing a connection location for vertical tensioning members  26  of the tensioning system and transferring a tensile load from the tensioning member to apply a compressive load to panels of the abutting side wall assembly  7  and end wall assembly  8 . The elongate connection element  36  may be formed with a hook shaped or “J” shaped anchor end  36 ′ and is also intended to interact or engage with the vertical tensioning members  26  by providing a connection location for tensioning members  26  of the tensioning system and transferring a tensile load from the tensioning member to apply a compressive load to panels of the abutting side wall assembly  7  and end wall assembly  8 . When assembled, the hook portion  34 ′ of the connection member  34  may interface with the hook portion  36 ′ of the elongate connection member  36  to form a common connection element. The corner bracket  32  may be generally “L” shaped and may comprise a corner bracket anchor element  38 , which may be hook shaped or “J” shaped and is intended to interact or engage with the lateral tensioning members  22  by providing a connection location for tensioning members  22  of the tensioning system and transferring a tensile load from the tensioning member to apply a compressive load to panels of the corner-abutting roof assembly  9   a  or floor assembly  9   b.  Generally, the tensioning member  26  that engages with the hook portions  34 ′,  36 ′ will extend in the vertical direction δ between vertically aligned corners, and the tensioning member  22  that engages with the corner bracket anchor element  38  will extend in the lateral direction β between adjacent corners. Although the hook portions  34 ′,  36 ′,  38 ′ are disclosed as hook shaped elements, the hook/anchor portions  34 ′,  36 ′,  38 ′ may be any shape to satisfy the minimum requirement of engaging with the tensioning members and bearing sufficient load such that the respective side wall assembly  7 , end wall assembly  8 , roof assembly  9   a  or floor assembly  9   b  is placed into compression. 
       FIGS. 4   a  and  4   b  are an exploded isometric view of an intermediate; butt-splice assembly and an isometric view of an assembled an intermediate, butt-splice assembly, respectively, of the framing system  5  of  FIG. 2   a .  FIG. 4   b  shows elements of the tensioning system  20  at the butt-splice assembly. The butt-splice assembly joins adjacent, co-linear framing members where they meet intermediate of the corner assemblies, and interfaces them with the tensioning system  20 . According to the depicted embodiments of  FIGS. 1-6 , an intermediate, butt-splice assembly between longitudinal frame members  51  may be substantially similar to an intermediate, butt-splice assembly between lateral frame members  53 . The skilled artisan will understand the few distinctions with reference to the discussion herein. 
     A typical butt-splice assembly for adjacent, collinear frame members  51  may include a pair of adjacent upper longitudinal frame members  51 , or a pair of adjacent lower longitudinal frame members  51  (alternatively, a pair of adjacent upper lateral frame member  53  or a pair of adjacent lower lateral frame member  53 ) and a butt-splice bracket  30 . With reference to  FIG. 4   a , the adjacent ends of the lower longitudinal frame member  51  may have a connection element  34  at each channel end and are brought together. The connection element  34 , similar to that described previously, have hook shaped or “J” shaped anchor end  34 ′ and is intended to interact or engage with the vertical tensioning members  26  by providing a connection location for tensioning members  26  of the tensioning system and transferring a tensile load from the tensioning member to apply a compressive load to the panels of an abutting side wall assembly  7 . When assembled, the hook portion  34 ′ of the connection member  34  may interface or contact with the hook portion  34 ′ of the adjacent connection member  34  to form a common connection element. The bracket  30  may be of a construction similar to corner bracket  32 , that is the butt-splice bracket  30  may be generally “L” shaped and may comprise a slot  31  (or multiple parallel slots) to accept therein the adjacent connection elements  34 , and a bracket anchor element  42 , which may be hook shaped or “J” shaped and is also intended to interact or engage with the lateral tensioning member  22  by providing a connection location for tensioning members  22  of the tensioning system and transferring a tensile load from the tensioning member to apply a compressive load to a panel of an abutting roof assembly  9   a  or floor assembly  9   b.  In its manner of assembly, the combination of butt-splice bracket  30  and two adjacent connection elements  34  perform at least the dual function of connecting adjacent co-linear frame members and anchoring tensioning members  22 ,  26 . Generally, the tensioning member  22  that engages with the bracket anchor element  42  of the bracket  30  and extends in the lateral direction β between spaced apart upper side channels  16  or between spaced apart lower frame members  51  and the tensioning member  26  that engages with the hook portion  34 ′ established by the adjacent connection elements  34  will extend in the vertical direction δ between vertically aligned frame members (i.e. either side wall assemblies or end wall assemblies). Although the hook/anchor portions  34 ′,  42  are disclosed as hook shaped elements, the hook/anchor portions  34 ′,  42  may be any shape to satisfy the minimum requirement of engaging with the tensioning members  22 ,  26  and bearing sufficient load such that the respective side wall assembly  7 , end wall assembly  8 , roof assembly  9  or floor assembly  9 ′ is placed into compression. 
     Collectively, the frame  5  and its subcomponents (lower and upper side channels  14 ,  16 ; front and rear channels  15 ,  17 ; corner posts  19 ; corner brackets  32 ; and brackets  30 ), the tensioning system and its subcomponents (tensioning members  22 ,  26 ), the wall panels  12  that form either side walls  7  or end walls  8 , the panels  13   a,    13   b  that form a portion of either the roof assembly  9   a  or the floor assembly  9   b  cooperatively function to produce a structure that is repeatably assembled and disassembled, modular, rigid when assembled, and transported in its component portions. In addition to tying the structure  10  together, the tensioning system functions to place the walls, floor and roof of the structure  10  into a compressive state of loading and strengthen the structure  10 . 
       FIGS. 3   a  and  3   b  are an exploded isometric view of a full corner assembly and an isometric view of an assembled full corner assembly, respectively, of the framing system  5  of  FIG. 2   a .  FIG. 5   b  shows elements of the tensioning system  20  at the full corner assembly.  FIGS. 3   a  and  3   b  illustrate more clearly the arrangement and relation of an upper corner assembly to a lower corner assembly as well as the tensioning members  22 ,  26  connected with the corner assembly and extending from the corner assembly. 
       FIGS. 4   a  and  4   b  are is an exploded isometric view and an isometric view, respectively, of cooperating upper and lower co-linear frame member butt-splice assemblies of the framing system  5  of  FIG. 2   a .  FIG. 4   b  shows elements of the tensioning system  20  at the butt-splice assembly.  FIGS. 4   a  and  4   b  illustrate more clearly the arrangement and relation of an upper channel assembly to a lower channel assembly as well as the tensioning members  22 ,  26  connected with the respective butt-splice assembly and extending from the assembly. The butt-splice assemblies of lateral frame members  53  are similar to the butt-splice assemblies of longitudinal frame members  51 . However, according to the depicted embodiments, the tensioning system associated with the lateral frame member  53  assembly does not comprise longitudinally extending tensioning members. 
     Experimental Assembly of the Structure: 
     The following describes an experimental assembly of the structure  10  of  FIG. 1  and provides one example of a process actually performed for assemblage of the structure  10  of the present disclosure. This assembly follows one example embodiment of an assemblage process, and is experimental in that it was timed and monitored. The present disclosure, and its related inventions are not limited to this sole assembly process nor are they limited by the specific components as used in this assembly process. Rather, one skilled it the art will understand acceptable variations, based on a reading and understanding of this entire specification and the accompanying drawings. 
     The structure  10  of this experimental assembly generally consists of pre-manufactured cap members  14 ,  15 ,  16 ,  17  and post members  19 , pre-manufactured floor, wall and roof panels  12 ,  13   a,    13   b,  pre-manufactured brackets  30 ,  32 , and pre-prepared tensioning straps and cables  22 ,  26 . For this assembly, the pre-manufactured panels  12 ,  13   a,    13   b  were polystyrene foam and steel composite panels. The floor panels were dimensioned, nominally, 16′×46″×6″ and were thicker than the wall and roof panels, which were dimensioned, nominally, 8′×46″×4″ and 16′×46″×4″, respectively. For this assembly, the cap members were structural channel members formed as double capture frame members  51 ,  53 ,  51 ′,  53 ′ as earlier defined; and for this assembly, the troughs of the floor channel members  15 ′,  17 ′ were wider than the troughs for the roof channel members  15 ,  17 . The components arrived at the building site as a package/kit ready to be assembled. The frame members  51 ′,  53 ′ containing the floor channel members  15 ′,  17 ′ were to be used to form an entire perimeter of a floor assembly  9   b  (in some embodiments, the floor assembly  9   b  may be comprised of a plurality of connected floor assemblies  9   b ). 
       FIGS. 20   a  through  20   r  illustrate aspects of the exemplary process of assembling the structure  10 . As assembly begins, an elevated and level base (see leveling bases  11 ) is prepared. As shown in  FIG. 20   a , a first floor panel  13   b  was laid out on respective leveling bases  11 , establishing the basic starting point, the location of the first end of the structure, and the lateral dimension. 
     Referring to  FIG. 20   b , opposing lower longitudinal frame members  51 ′ were placed on respective bases  11 , one on each side of the first floor panel  13   b,  and the opposing lower longitudinal frame members were pressed against the first floor panel capturing the longitudinal side portions of the first floor panel in the troughs of the respective channel members of the lower longitudinal frame members. A pair of collinear lateral frame members  53 ′ were arranged perpendicular to the longitudinal frame members  51 ′, pressed onto the lateral end portion of the first floor panel  13   b,  and joined with first ends of the two opposing longitudinal frame members  51 ′ using corner brackets  32 . The distance between the opposing longitudinal frame members  51 ′ required two, collinear lateral frame members  53 ′, and they were adjoined with one another using a butt-splice bracket  30 . 
     Referring to  FIG. 20   c , a second floor panel  13   b  was introduced to the two opposing frame members  51 ′, spanning the distance there-between, by sliding the front-side section and rear-side section of the panel into the trough regions of the respective channel members of the opposing frame members  51 ′, thereby capturing the longitudinal side portions of the second floor panel in the respective channel member. The second floor panel  13   b  was slid toward the first end of the two opposing frame members  51 ′, until the second floor panel abutted the first floor panel  13   b . Subsequent floor panel(s)  13   b  were similarly introduced and slid into place in the same opposing frame members  51 ′, so that the opposing frame members  51 ′ accommodated three floor panels  13   b . Each panel (whether it be a wall panel  12 , roof panel  13   a  or floor panel  13   b ) was formed with an interlocking edge by which one panel&#39;s edge engages with (actually slips inside) an adjacent panel edge; and this “engaging joint” was employed by pushing together the adjacent panels. 
     Referring to  FIG. 20   d , as each section of floor section/assembly  9   b  was assembled (e.g., three floor panels  13   b  were captured by the pair of opposing longitudinal frame members  51 ′), a second longitudinal frame member  51 ′ was abutted, in collinear orientation, to each of the already in place longitudinal frame members. Referring to  FIGS. 20   e  through  20   g,  a butt-splice bracket  30  was placed over the adjacent connection elements  34 , and a lateral tensioning member  22  was connected between the opposing frame members  51 ′ (from bracket connection element  42  to connection element  42 ) of the assembled section. The tensioning member  22  used on the floor panels was wire cables with an intermediate turnbuckle; and the tensioning member was tightened by hand, through hand activation of the turnbuckle, to pull the opposing frame members  51 ′ on each side of the structure  10  together and place the first floor section/assembly  9   b  in compression. The tightening of the tensioning system  20  provides strength of the system. Next, the floor panels  13   b  of the adjacent floor section/assembly  9   b ′ were added, in a manner similar to the first floor section. As each of the collinear frame members  51 ′ of floor was linked together, a bracket  30  captured and secured each end of the adjacent and connecting collinear frame members. The bracket  30  not only captured the ends of the adjacent collinear frame members  51 ′, but also provided a compression tie point for the lateral tensioning members  22  to compress the respective floor panels  13   b.  This procedure was repeated until the floor (all intended sections) was completed, except for including the final pair of lateral frame members  53 ′. Two technicians typically handled each floor panel, one at each side (front/back) edge, placing the opposing side sections into the respective channel member trough and sliding the panel into place. 
     Referring to  FIG. 20   h , the final pair of lateral frame members  53 ′ for the floor were installed to cap the exposed lateral edge of the last installed floor panel  13   b.  To accomplish this closure, two, collinear, lateral frame members  53 ′ were arranged perpendicular to the longitudinal frame members  51 ′ and joined with the ends of the two opposing longitudinal frame members  51 ′ using corner brackets  32 . The final pair of lateral frame members  53 ′ were collinear and adjoined end-to-end with one another using a butt-splice bracket  30 . Again, a cable tensioning member joined the opposing longitudinal frame members  51 ′ and was tightened, by hand, to place the captured floor panels in compression. At the corners, the corner brackets  32  were utilized to hold the adjacent connection elements  34 ,  36 , and a lateral tensioning member connected with the respective anchors  38 ,  38 . 
     Referring to  FIGS. 20   i  and  20   k , after the floor assembly  9   b  was constructed; the wall panels  12  were slid from above into the upwardly open troughs of the upwardly facing channel members of the frame members  51 ′,  53 ′ that now established the perimeter of the floor assembly  9   b . As each wall panel was introduced into the respective upwardly open trough, it was slid tightly against the adjacent wall panel, taking advantage of the aforementioned engaging joint. One technician easily handled and lifted a single eight foot wall panel  12  into position and slid it into the engaging joint of the adjacent panel  12  already in an installed position in the framing system  5 . 
     Referring to  FIG. 20   j , one at a time, beginning at one end of the structure, the upper frame members  51 ,  53 , which are for eventually capturing the roof panels  13   a,  were placed on top of the wall panels  12 . As each section of wall assembly  9   b  was assembled (e.g., three panels were captured by the pair of vertically opposed longitudinal frame members  51 ,  51 ′), a second frame member  51  was abutted, in collinear orientation, to the respective already in place frame member  51 ; a butt-splice bracket  30  was placed over the adjacent connection elements  34 ; and a vertical tensioning member  26  was connected between the vertically opposing frame members  51 ,  51 ′ (from bracket connection anchor  34 ′ to connection anchor  34 ′) of the assembled section, as may be understood with reference to  FIG. 20   l.    
     Referring to  FIG. 20   o , at the corners of the structure  10 , before the respective upper, lateral frame members  53  were set in place, corner posts  19  were installed in each of the corners by sliding the double channel post members onto the respective end and side wall panels  12  from above. After the end wall sections  8   a  that form one end of the structure  10  and a few side wall sections  7   a  abutting the end sections  8   a  of the structure  10  were in an installed position and capped by the respective upper frame members  51 ,  53  (e.g., so that the upper portions of the walls  12  are respectively received in the downwardly open troughs of the downwardly facing channel members of the frame members  51 ,  53 ) roof panels  13   a  were installed. No special hoisting equipment was needed, only a few step ladders. The roof panels were installed much the same as the floor panels  13   b,  with two technicians typically handling each roof panel, one at each side (front/back) edge, simultaneously placing the opposing end sections into the respective channel member trough, with the aid of a step ladder, and sliding the panel toward the first end of the structure and into place. Alternatively, the edges of roof and floor panels  13   a,    13   b  may be installed one at a time, by placing one of the opposing end sections into the respective channel member trough, followed by placing the other of the opposing end sections into the respective channel member trough. To avoid accidental tipping of the end wall, a technician was in attendance by the first-end wall until the first section of roof was installed. 
     Before the final roof panel  13   a  was installed, the final wall panels  12  for the still open end (wall assemblies  8   b ) were installed, allowing for the final corner posts  19  to be installed. Then, the final roof panel  13   a  was slid into place, and the final two lateral frame members  53  were positioned and the respective corner and butt-splice brackets installed. Referring to  FIG. 20   q , at the corners, the corner brackets  32  were utilized to hold the adjacent connection elements  34 ,  36 , and a vertical tensioning member connected with the respective anchors  34 ′,  36 ′. The vertical tensioning member  26  used on the wall panels  12  was a fabric strap with mechanical ratchet; and the tensioning member was tightened by hand, through hand activation of the ratchet, to pull the opposing frame members at the top and bottom of the structure  10  together and place the wall sections in compression. 
     The system of butt-splice brackets  30  and horizontal tensioning members  22  used to assemble the floor assembly  9   b  were similarly used throughout assembly of the roof sections. The final tensioning members were connected and all tensioning members hand tightened to place all floor, wall and roof assemblies in compression in both the lateral β and vertical directions δ. Since all wall panels  12  are interchangeable, final placement of panels containing doors and windows were determined at the time of installation. 
     For this experimental installation, taking just over  68  minutes, a  685  square foot temporary or semi-permanent structure  10  was erected, using four and sometimes five technicians.

     For each of the previously discussed embodiments, one or more of the floor, wall and roof assemblies may optionally be replaced with a fixed structure, such as a conventional fixed floor (e.g., concrete slab), a conventional fixed wall and/or a conventional fixed roof, to provide numerous other embodiments of this disclosure. For example,  FIGS. 21-24 ,  25   a  and  25   b  illustrate aspects of a fourth embodiment that is like the first embodiment (e.g., see  FIGS. 1 ,  2   a ,  2   b ,  3   a ,  3   b ,  4   a ,  4   b ,  19   a ,  19   b ,  19   c ), except for variations noted and variations that will be apparent to one of ordinary skill in the art. For example, the modular structure  10  of the first embodiment may be characterized as being freestanding, or at least relatively freestanding as compared to a modular structure  310  of a fourth embodiment, which is for being fixedly mounted to a fixed upright structure that may be a fixed wall  307 . The fourth embodiment is like the first embodiment, except that the side wall assembly  7   a  of the first embodiment is replaced with the fixed wall  307  to which the modular structure  310  of the fourth embodiment is attached. The fixed wall  307  may be any suitable conventional wall, such as a masonry, concrete and/or steel wall that is sufficiently strong for having the modular structure  310  mounted thereto. For example, the fixed wall  307  may be part of a conventional building to which the modular structure  310  is attached. 
     The framing system  305  of the fourth embodiment is like the framing system  5  of the first embodiment, except, for example, at the side for being mounted to the fixed wall  307  the corner posts  19  and frame members  51 ,  51 ′ of the first embodiment are replaced with fixedly mountable corner posts  319  and fixedly mountable frame members  351 ,  351 ′. The corner posts  319  and frame members  351 ,  351 ′ each may include or define an elongated, open channel or trough, or shoulder, along the length thereof for receiving or otherwise supporting the respective edge of the associated wall, roof or floor panel  12 ,  13   a  or  13   b.  Each of the corner posts  319  and frame members  351 ,  351 ′ include at least one flange with one or more holes or notches for having fasteners  375 , such as bolts, extend therethrough. The fasteners  375  are for penetrating into and becoming fixedly mounted to the fixed wall  307 , for mounting the corner posts  319  and frame members  351 ,  351 ′ to the fixed wall. The frame members  351 ,  351 ′ have connection elements  34  at their ends for holding onto respective ends of tensioning members  22 . 
     The framing system  305  of the fourth embodiment is like the framing system  5  of the first embodiment, except, for example, the frame members  53 ,  53 ′ of the first embodiment that would be adjacent to the corner posts  319  are replaced with frame members  353 ,  353 ′ that include at least one flange with one or more holes or notches for having fasteners  375 , such as bolts, extend therethrough. The fasteners  375  are for penetrating into and becoming fixedly mounted to the fixed wall  307 , for mounting the frame member  353 ,  353 ′ to the fixed wall. The frame members  353 ,  353 ′ further include connection elements  34  at their ends adjacent the fixed wall  307  for holding onto respective ends of tensioning members  22 . 
     The connection elements  34  may be an integral part of the frame members  351 ,  351 ′,  353 ,  353 ′ or the connection elements may be mounted to the respective frame members in any suitable matter, such as by welding. In addition or alternatively, the frame members  351 ,  351 ′,  353 ,  353 ′ may extend from brackets or flanges that are connected to the frame members  351 ,  351 ′,  353 ,  353 ′ in any suitable manner, such as by welding, by way of respective ones of the fasteners  375 , and/or in any other suitable manner. 
     The above examples are in no way intended to limit the scope of the present invention. It will be understood by those skilled in the art that while the present disclosure has been discussed above with reference to exemplary embodiments, various additions, modifications and changes can be made thereto without departing from the spirit and scope of the invention as set forth in the claims.
