Description

Single layer lattice shell structures with pin joints have a light feeling, little weight, apparent resistance only by axial forces and simple connections. The good performances often apply to structures for long span roofs. The structures subjected to external loads often show instability phenomena such as buckling. They cannot make plane shapes that resist external loads by bending moments. In this paper, a new single layer lattice shell structure that can make any shape is suggested Tensile members supporting bending moments reinforce the single layer lattice shell with pin joints. Initial stresses make it a self-supported structure. Structural characteristics are verified by numerical , analysis, construction tests and loading tests.
