Abstract

Abstract

Considering the effect of covering membrane based on the cable-supported structure without inner hoop, the collaborative form-finding analysis of the whole model was carried out, and the steps of collaborative form-finding were given. The rationality of the results of the form-finding was demonstrated. Finally, static analysis, parametric analysis and dynamic analysis of the structure were carried out. The results showed that cable-supported membrane roof could resist external loads, but considering the drainage of membrane, folds and the area of single membrane, the structure was more suitable for small and medium span structures. Membrane self-weight, Poisson's ratio and prestress of side cables had little influence on cable-supported membrane roof, but elastic modulus and initial prestress of membrane had great effects on membrane roof. The vibration modes of the structure were mainly upward and downward vibration accompanied by local torsion of planar cable-truss frame, so there were no adverse effect on the force of integral structure.
