Static behavior analysis of a new annular tensile cable-truss structure

The development and engineering applications of large-span annular tensile calbe-truss structural system are introduced and a new type of annular tensile cable-truss structures is proposed. The new structural system is to reduce the space occupied by roof structure and could be laid by the rigid roofing material easily.Two types of annular tensile cable-truss structure, Ribbed and Sunflower-patterned cable-truss structure, were given. Ribbed cable-truss structure 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.
