Abstract:
1. A portable structure having sufficient internal structural rigidity to eliminate load-bearing perimeter support structure, the portable structure comprising: first and second rigid frames, each of the first and second rigid frames including: a carriage assembly, the carriage assembly supporting a floor diaphragm coupled thereto, the carriage assembly being rigidly coupled to the lateral floor joist supports of each of the first and second frames; at least two mutually parallel horizontal roof supports supporting a roof diaphragm, the horizontal roof supports being substantially perpendicular with, and rigidly coupled to, the lateral roof supports of the first and second rigid frames; and at least one set of leveling assemblies configured to support said portable structure when in a stationary mode, each of the at least one set of leveling assemblies configured to be in weight-bearing and in-line relationship with respect to one of the vertical supports of one of the first and second rigid frames, whereby whenever the leveling assemblies are extended to and rigidly coupled to the ground, substantially all lateral forces imposed on said portable structure are transferred to the ground through the one of the first and second rigid frames.
