A modular building structure is provided. The building structure has a support framework comprising a pair of longitudinally extending beams, a plurality of vertically and transversely extending identical arched ribs spaced apart from one another, a plurality of level one joists coupled at each transverse end to one of the ribs and one of the beams, a plurality of level two joists coupled at each transverse end to one of the ribs at a location above the level one joists, and a plurality of longitudinally extending hat bars coupled to the transverse insides of all of the arched ribs. The hat bars may have a generally trapezoidal cross-section. The beams, arched ribs, level one joists, level two joists, and hat bars are preformed and provided with pre-drilled holes for coupling to other components of the support framework. Methods and kits for building a modular building structure are also provided. |
