DOMES
A dome is a curved roof which encloses a circular space. A dome must support its own dead load as well as the live load of wind, rain, snow, or ice. A geodesic dome distributes loads over all of the different triangles that comprise it. Triangles are very stable shapes. It is difficult to distort a triangle; compression at one joint is balanced by tension along the opposite side.
