Static behavior analysis of a space structure composed of annular tensile cable-truss structure and single layer lattice shell

A new type of space structure combined with annular tensile cable-truss structure and single layer lattice shell is introduced. The new structural system is to reduce the space occupied by roof structure and could be laid by the rigid roofing material easily. And then a series of new composite spatial structures composed of the annular tensile cable-truss structure and other spatial structure are proposed. Ribbed composite spatial structures combined with annular tensile cable-truss structure and single layer lattice shell was taken as an example and its static behavior under full-span load and half-span load was analyzed. The effect of prestress level on static behavior of the structure was studied. The results will provide a reference for a further design and project application of such structure.
