DETAILED DESCRIPTION
Embodiments of the present disclosure provide a load bearing structural assembly having an array of arcuate members arranged in a configuration to resist forces in bending. The members are arranged to distribute forces more evenly to the overall force resisting structural assembly. The assembly of members is arranged between an outer member and an inner member so as to distribute the load more equally through the load bearing structural members and to the force resisting structural assembly. A web of arcuate members is located between the inner and outer members and is configured having a spacing, quantity and/or size to accommodate force resisting and deflection requirements. According to one embodiment, a load bearing structural assembly includes an outer loop member, an inner loop member spaced apart from and sized smaller than the outer loop member, and a web assembly coupled to and extending between the outer loop member and the inner loop member, where the web assembly comprises a plurality of arcuately formed web members.
With reference now to the Figures and in particular with reference to FIGS. 1 and 2, exemplary diagrams of a load bearing structural assembly 10 according to the present disclosure are provided. FIG. 1 is a diagram illustrating an embodiment of assembly 10 according to the present disclosure, and FIG. 2 is a diagram illustrating an isometric view of assembly 10 illustrated in FIG. 1. In FIGS. 1 and 2, assembly 10 is depicted as a substantially planar arrangement of structural elements and comprises an outer loop member 12 and an inner loop member 14. In FIGS. 1 and 2, outer loop member 12 and inner loop member 14 are generally circular in shape and located concentric relative to each other such that outer loop member 12 is larger than and located spaced apart from a smaller inner loop member 14 by a desired distance (e.g., to efficiently distribute load in the directions of 16 and 18). It should also be understood that in some embodiments, loop member 12 and/or loop member 14 may be slightly non-circular (e.g., slightly elliptical) and may be located non-concentric relative to each other. In the illustrated embodiment, a shear web assembly 20 is located between and connects outer loop member 12 and inner loop member 14. In the illustrated embodiment, shear web assembly 20 comprises a plurality of web members 22 and a plurality of web members 24. Web members 22 are arcuately formed having a concave face 30 facing outwardly toward outer loop member 12. Web members 24 are arcuately formed having a concave face 32 facing inwardly toward inner loop member 14. In some embodiments, web members 22 and 24 are configured as circular and/or partially circular members (e.g., having a constant and/or fixed radius of curvature); however, it should be understood that web members 22 and/or 24 may be slightly non-circular (e.g., elliptical). In the illustrated embodiment, six web members 22 and twelve web members 24 are illustrated. However, the quantity and/or sizing of web members 22 and 24 may vary (e.g., to accommodate load and deflection requirements). Additionally, in the illustrated embodiment, a radius of curvature of web members 24 is less than a radius of curvature of web members 22.
In the illustrated embodiment, each end of a particular web member 22 is coupled to outer loop member 12 (e.g., at location 34), and web members 22 are sized having a length such that ends of adjacent web members 22 terminate at (or near) a common/coincident location relative to outer loop member 12 (e.g., at location 34). A medial location 36 of each web member 22 is coupled to inner loop member 14. In the illustrated embodiment, web members 22 are formed as a continuous element having each end thereof coupled to outer loop member 12 and a medial location thereof coupled to inner loop member 14; however, it should be understood that in some embodiments, web member 22 may be formed from multiple components/elements along its length (e.g., a first element extending from outer loop member 12 to inner loop member 14, and another element extending from inner loop member 14 to outer loop member 12).
Web members 24 are each sized such that one end thereof terminates and is connected to medial location 36 of web member 22 while an opposite end thereof terminates and is connected to outer loop 12 at location 34. Thus, as illustrated in FIG. 1, ends of adjacent web members 24 terminate at (or near) a common/coincident location (e.g., with ends of adjacent web members 22 at a particular location 34).
FIG. 3 is a diagram illustrating an embodiment of a load bearing structural assembly 40 including multiple assemblies 10 according to the present disclosure. In the embodiment illustrated in FIG. 3, assembly 40 includes three assemblies 10 (e.g., assembly 101, 102 and 103) coupled together at (or near) tangential locations along adjacent outer loop members 12 of respective assemblies 10. As illustrated in FIG. 3, each assembly 10 includes outer loop member 12, inner loop member 14 and web members 22 and 24 (e.g., as depicted in FIGS. 1 and 2). Assembly 40 also includes loop members 42 and additional web members 22 and 24 that may be coupled at various locations relative to assemblies 10 to form an array of structural elements. For example, in the illustrated embodiment, additional web members 22 (e.g., web member 221) may be positioned to extend from an outer location of one loop member 12 (e.g., location 44) to an outer location of another loop member 12 (e.g., location 46) at various locations of assembly 40. Further, web members 24 (e.g., web members 241 and 242) may be located relative to such web members 22 (e.g., web member 221) such that web members 24 extend from location 44 to location 46. For example, web member 241 extends from location 44 to a medial location 48 of web member 221, and web member 242 extends from medial location 48 to location 46. This arrangement of web members 22 and 24 may be located at various positions of assembly 40.
Additionally, as illustrated in FIG. 3, loop members 42 are coupled to the convex faces/locations of various web members 24, thereby extending between and coupling together adjacently located shear web assemblies 20 of adjacent assemblies 10. For example, in the illustrated embodiment, a particular loop member 42 is coupled to convex face/locations of web members 241 and 242, to convex faces/locations of web members 243 and 244 of assembly 103, and to convex faces/locations of web members 245 and 246 of assembly 101. Thus, in the illustrated embodiment, this arrangement of a particular loop member 42 with associated web members 22 and 24 form smaller circular arrangements of structural elements (e.g., with web member 221, web member 222 of assembly 103 and web member 223 of assembly 101 forming an outer loop, loop member 42 forming an inner loop, and web members 241-246 forming a web assembly between the outer and inner loops). These additional smaller loop arrangements (e.g., smaller than assemblies 10) may be located at various locations about assembly 40. Loop members 42 may be circular (i.e., having a constant radius of curvature) or slightly non-circular.
In FIGS. 1-3, outer loop members 12, inner loop members 14, web members 22 and 24, and loop members 42 are each depicted as being formed and/or constructed as single/unitary structures or elements. However, it should be understood that each of outer loop member 12, inner loop member 14, web members 22 and 24 and/or loop members 42 may be formed from multiple components/elements and/or having various cross-sectional geometries. For example, FIG. 4 is a diagram illustrating an embodiment of outer loop member 12 in accordance with the present disclosure. In the embodiment illustrated in FIG. 4, outer loop member 12 is formed from three arcuately formed elements 50, 52 and 54 coupled together to form a triangular-shaped cross section for outer loop member 12. Elements 50, 52 and 54 may be configured with any desired radius. It should be understood that a similar triangular-type cross section may be used to form inner loop members 14, web members 22 and 24 and/or loop members 42. It should also be understood that other cross-section arrangements/elements may be used to form outer loop member 12, inner loop member 14, web members 22 and 24 and/or loop members 42 (e.g., ninety degree angle element(s), I-shaped element(s), T-shaped element(s), circular and/or oval element(s), etc.). Outer loop member 12, inner loop member 14, web members 22 and 24 and/or loop members 42 may be formed from any desired structural material with a desired level of flexure to thereby enable bending with some desired level of rigidity (e.g., steel elements/plates, fiber reinforced polymer elements, cured/aged bamboo, and/or other types of materials).
Outer loop member 12, inner loop member 14, web members 22 and 24 and/or loop members 42 may also be formed to enable/facilitate attachment to each other and/or therebetween. For example, FIG. 5 is a diagram illustrating a cross sectional view of a T-shaped embodiment of outer loop member 12 according to the present disclosure. In the illustrated embodiment, outer loop member 12 is formed from two ninety degree-shaped elements 60 and 62 such that elements 60 and 62 each have an outward flange 64 and 66, and an inward flange 68 and 70, respectively. In this embodiment, a gap or space 72 is formed between opposing faces of flanges 68 and 70, thereby enabling an element of web members 22 and/or 24, for example, to be located and/or positioned therein to facilitate attachment of web member 22 and/or 24 to loop member 12. It should be understood that the various elements/components of assemblies 10 and 40 may be otherwise configured to facilitate attachment to each other.
Thus, in operation, the load bearing structural assembly of the present disclosure comprises a force resisting system that more efficiently and evenly distributes forces, thereby enabling more efficient use of materials and resisting of forces, as well as a greater limit of deflection. For example, embodiments of the present disclosure provide a load bearing structural assembly that is analogous to a spring laid on its sides, but in a vertical plane, used to store and release energy with movement. The load bearing structural assembly of the present disclosure provides resistance to movement in the elastic range of the material. The load bearing structural assembly according to the present disclosure stores energy more evenly in the assembly while enabling movement to occur through bending, in the elastic range, without yielding, and without exceeding the limits of eccentricity. The load bearing structural assembly according to the present disclosure also includes a number of members that provide redundancy in design. The increased strength of the load bearing structural assembly according to the present disclosure is derived from a repetitive loop configuration and the efficiency generated through the mechanics of the loop which enables controlled movement. The loop design of the present disclosure offers efficiency in material use while optimizing tension/compression/bending forces through the loops.
For example, in some embodiments, loop members 12 and 14, web members 22 and 24, and/or loop members 42 are configured to enable bending with a prescribed level of rigidity. As an example, loop members 12 and 14, web members 22 and 24 and/or loop members 42 may be configured as depicted in FIG. 4 having a triangular configuration, thereby a desired level of rigidity. Loop members 12, 14 and 42 and web members 22 and 24 can be sized and numbered/distributed according to several factors for the particular application, such as the load 18 applied to the load bearing structural assembly, the load 16 applied and to be distributed through the load bearing structural assembly, the limits in member (e.g., loop members 12, 14 and 42 and web members 22 and 24) and assembly 10/40 deflection. The load bearing structural assembly of the present disclosure is configured to deflect in bending with a greater allowed eccentricity due to the circular nature of loop members 12, 14 and 42 and web members 22 and 24 while avoiding significant loss of strength (e.g., such as experienced in the limited eccentricity allowed by post and beam designs). The strength of the load bearing structural assembly of the present disclosure is achieved from the greater allowable bending due to the external loads 16 and 18, and achieved through the circular nature of loop members 12, 14 and 42 and web members 22 and 24, which enables greater load eccentricity. The size and/or configuration of loop members 12, 14 and 42 and web members 22 and 24 may be selected based on the maximum load which must be carried by any one section. In other words, the load bearing structural assembly is designed in view of the strength required to resist the forces to be encountered, and other loading specific to the certain application.
Outer loop 12 is configured to hold the partial assembly (e.g., loop member 14 and shear web 20) in tension and have the required resistance in shear. The cross section area and thickness of loop member 12 (e.g., if a “T” cross section, the cross section of the upper flange and the cross section of the vertical flange) can be adjusted along the length to maximize the use of the material or maintained at a constant value to maximize the speed of construction. The modulus of elasticity, moment of inertia, cross section area, and yielding strength of loop member 12 can be selected/configured according to required loading, deflection, etc.
Web members 24 are configured to transmit shear, resist bending, and transfer forces more evenly between outer loop member 12 and inner loop member 14. For example, web member 24 configured having a “T” cross section may include a tension element (the upper flange of the “T”) and a shear element (the vertical flange of the “T”). The section properties of any particular flange, cross section area of the overall member 24 and/or thickness can be adjusted along the length of web member 24 to maximize the use of the material or maintained at a constant value to maximize the speed of construction as required for the performance of the load bearing structural assembly 10/40. The properties of web member 24 may be configured/selected according to required loading, deflection, etc. The shape of web member 24 in section could be represented by back to back “L”-shaped elements separated by a space for connection purposes or be otherwise configured.
Web members 22 are configured to transmit shear, resist bending, and transfer forces more evenly between the outer loop member 12 and inner loop member 14 as well as link the components together (e.g., outer loop member 12, inner loop member 14, web member 24 and/or loop members 42) to form a larger force resisting assemblage (e.g., as illustrated in FIG. 3). Web member 22 may be configured having a “T” cross section with a tension element upper flange and a shear element vertical flange. The section properties of the upper and vertical flanges of web member 22, the overall cross section area of web member 22, and/or thickness can be adjusted along the length of web member 22 to maximize the use of the material or maintained at a constant value to maximize the speed of construction as required for the performance of load bearing structural assembly 10/40. Web members 22 may be configured by back-to-back “L”-shaped elements with a space therebetween for connection purposes or may be otherwise configured.
Inner loop member 14 is configured to resist primarily shear and compression forces due to the bending of outer loop member 12. For example, inner loop member 14 may also be configured having a “T” cross section with an upper flange and a vertical flange where the compressive forces are resisted in shear primarily by the vertical flange of the “T.” The upper flange of the “T” controls bending to a lesser extent, and the vertical flange of the “T” to control shear. The section properties of the upper and vertical flanges, the overall cross section of loop member 14 and/or thickness may be adjusted along the length of loop member 14 to maximize the use of the material or maintained at a constant value to maximize the speed of construction as required for the performance of load bearing structural assembly 10/40 and to accommodate required loading, deflection, etc.
Outer loop members 12, inner loop members 14, loop members 42 and web members 22 and 24 are configured and/or designed to be able to bend with some rigidity while not being overly stiff and not exceeding the greater allowed eccentristic loading of the particular members. The assemblage of members 12, 14, 22, 24 and 42 is configured to enable and limit deflection in a truss type arrangement of bending members. The load bearing structural assembly of the present disclosure enables in-plane movement and has a much greater allowable eccentricity of loading due to the loop nature of the assembly. The diameter/radius of the respective members 12, 14, 22, 24 and 42 can vary according to space and strength requirements. The load bearing structural assembly of the present disclosure provides greater strength resulting from the bending of the members 12 and 14 while being braced against over bending by the shear web assembly 20 and allows a great eccentricity of loading. The modulus of elasticity, moment of inertia, cross section area, and yielding strength of members 12, 14, 22, 24 and 42 can be selected to develop a desired deflection, which can be much more than an axially loaded column can absorb, and still stay in the elastic range. The loop configuration of members 12, 14, 22, 24 and 42 enables a much greater deflection to be taken before failure and enables an even distribution of forces among members 12, 14, 22, 24 and 42.
FIG. 6 is a diagram illustrating an embodiment of assembly 10 connected to a base 80. In some embodiments, to realize the energy input into and through assembly 10/40, a form of base 80 where the final energy can be stored and/or resolved is utilized. Base 80 may comprise a variety of forms (e.g., building foundation, gearing holding, or other structures) which have a mass to absorb and distribute loading and will generally be of greater mass than the members 12, 14, 22, 24 and 42. Base 80 may comprise an integral part of assembly 10/40 and the connection thereto (e.g., to inner loop member 14) can be similar to the shear connection and spaced at desired intervals along the inner loop member 14. For example, FIG. 7 is a diagram illustrating a section view of an embodiment of a connection of inner loop member 14 to base 80 taken along the line 7-7 of FIG. 6 according to the present disclosure. In FIG. 7, inner loop member 14 is configured having a “T” cross section with an upper flange 82 and a vertical flange 84. Upper flange 82 may be secured to base 80 using fasteners 86. However, it should be understood that other configurations/shapes of inner loop member 14 may be used, and other methods of securing/coupling inner loop member 14 to base 80 may be used (e.g., welding, clamps, etc.).
FIG. 8 is a diagram illustrating an embodiment of a coupling system 90 for assembly 10/40 (FIG. 1) according to the present disclosure, and FIG. 9 is a diagram illustrating a section view taken along the line 9-9 of FIG. 8. In the illustrated embodiment, coupling system 90 is provided to absorb and release energy input into assembly 10/40. For example, in the event a greater allowable deflection is needed from assembly 10/40 due to loading conditions, a greater eccentricity can be provided. System 90 can be used for dissipation of energy through added deflection. In the illustrated embodiment, system 90 comprises a spring-based attachment element including a coupling element 92 in combination with springs 94 (e.g., between opposing loop members 12 and on opposite sides of web members 24). System 90 may be an assortment of materials and shapes used to store and release kinetic and potential energy into and from assembly 10/40. The equilateral triangular alignment of these axial attachments (e.g., attachment of adjoining loop members 12) and the side bearing loads 96 (FIG. 3) between adjoining loop members 12 enables minimal bending while generating the maximum axial elongation of system 90. This elongation can be managed by the stiffness and the length of system 90. The needed rigidity of system 90 will be dependent on the loading of assembly 10/40, the length of system 90, and the allowable deflection generated through the greater eccentricity of the loading.
FIG. 10 is a diagram illustrating an isometric view of load bearing structural assembly 40 placed into a building frame system 100 according to the present disclosure, and FIG. 11 is a diagram illustrating a view of a portion of frame system 100 of FIG. 10. In the illustrated embodiment, assembly 40 is integrated into system 100 by bracing assembly 40 against frame system 100 and a base 102. Base 102 is used to store and resolve the energy input into and released from assembly 40. In the illustrated embodiment, energy is stored and released by assembly 40 into base 102 via system 90. For example, FIG. 12 is a diagram illustrating a section view of an embodiment of a coupling of assembly 40 to base 102 taken along the line 12-12 of FIG. 11 using system 90 according to the present disclosure. In this embodiment, assembly 40 releases energy into the base 102 through coupling members 92 anchored in base member 102. The energy input into assembly 40 is also released in the movement of assembly 40 within and against itself. FIG. 13 is a diagram illustrating a section view of an embodiment of assembly 40 braced against frame system 100 taken along the line 13-13 of FIG. 11 according to the present disclosure. In FIG. 13, assembly 40 is coupled to frame system 34 via support members 104 extending between and coupled to adjacent support members 106 of frame system 100. Thus, in operation, assembly 40 is coupled to frame system 100 without fixity and is allowed to move in the direction indicated by 110 within the direction of frame system 100 strength indicated by arrow 112.
Embodiments of the assembly 10/40 of the present disclosure may be used in a variety of applications including, but not limited to, seismic resistance of forces in buildings, systematic release of forces in gears of machines, etc. As an example, assembly 10 may be configured in a wide array of sizes and incorporated into a building frame system (post and beam) to serve the strengths noted above. The size can vary depending on the size/space limitations and forces being handled (e.g., sized into a half story of a building to extending across multiple stories in a building frame system). In addition, assembly 10 may serve as a gear in an overall system with release and channeling of forces along inner loop member 14 and outer loop member 12. As described above, assembly 10/40 can store and release energy in the elastic range and provides predictable movement in this energy transfer between respective gears. While portions of this disclosure of assembly 10/40 are depicted and described for clarity and convenience in two dimensions, assemblies 10/40 according to the present disclosure may be configured in three dimensions to accommodate desired applications (e.g., as depicted in FIG. 2).
