Spheres are a visually attractive, structurally efficient & an often found application in Theme Parks, Theatres, Religious Buildings, Malls, Building features & Signage. Various geometrical arrangements can be developed with a triangle as the basic structural element. Geodesic domes are arranged so that every line of members around the sphere divide it in half & all member and joints are identical.
Modern technologies allow all shaped structures to be developed very economically with differing members and joints. Lamella geometry is often considered more aesthetically pleasing & is more practical to build. Schwedler geometry is sometimes preferred for small glazed structures. Structural design assumes loads are transferred axially through the shell which results in very efficient design-lighter structural members & less load on foundations. The ability to quickly construct Triodetic spheres in pre-assemblies also reduces cost and time.
