Abstract
A self supporting dome structure comprised of a plurality of rings connected one upon another, each of the rings approximating a conical frustum with successively higher rings having lower angles of inclination. Many of the rings are formed of a plurality of individual, flat panel, each of which includes a flat rectilinear top plate member, a flat rectilinear bottom plate member and opposed flat rectilinear side members, the side member converging inwardly from the bottom member to the top member. The structure includes at least one first transitional ring having a plurality of panels, each panel of the transitional ring including upwardly converging rectilinear side members, a concave top plate member defining an upper conical surface which slopes inwardly, and a flat rectilinear bottom plate, and at least one second transitional ring having a plurality of panels, each panel of the second transitional ring including upwardly converging rectilinear side members, a flat rectilinear top plate member and a convex bottom member defining a lower conical surface which slopes inwardly. The rings above the transitional ring having fewer panels than the rings below the transitional rings.
