Abstract
A folding dome-like modular building structure composed of 48 flexibly interconnected equal right isosceles triangles. Each building structure is formed from a series of four flexibly connected modules of 12 triangles each. The modules are connected in alternating right and left-handed mirror image sequence. Each triangle may be a rigid panel or an open space enclosed by struts or panel edges. The structure may be formed in part from struts and in part from panels. It may be an open or partially open framework or it may be enclosed by fabric or film supported over or suspended from the framework.
