Abstract：Based on experimental test of qualitative model and finite element analysis of the archetypal structure of Foshan Century Lotus Stadium, the progressive collapse property and the dynamic response of a wheel-spoke cable-membrane structure were systematically studied when its main members were failure. The results show that the order of the importance of the structure’s main components from small to big is the hanging cables, the truss web, the lower compression ring, the upper compression ring, the column, the divaricating cable, the upper radial cable, the lower radial cable, and the inside cables. The degree of the damage caused by the important members breaking from small to big is the breaking of one lower radial cable, one upper radial cable, two neighboring lower radial cables, two neighboring upper radial cables, column, two neighboring radial cables, three neighboring radial cables, the inside pull cables. The structure has good collapse-resistant property. After the breaking of important members, their loads could be rapidly transferred to the neighboring members. And the collapse range was preferably restricted in limited region. Double cables system, zone-design, and multi-columns style pier could improve the collapse-resistant performance of the structure.
