Abstract:The overall shape of the cable-membrane structure of Moon Bay City Balcony Project in Wuhan is a special-shaped curved surface, which is a large-span flexible structure. The cable-membrane structure is mainly composed of load-bearing cables, stabilizing cables and surrounding trusses as rigid supports. Under the action of dead loads, the maximum stress of the pipe truss member appears near the support and the stress of the rod is mainly pressure. Firstly, the design of the cable-membrane structure  of the balcony was introduced in detail, and the static and stability analysis of the cable-membrane structure under different load conditions were carried out. Then the typical joints were selected from the steel truss structural columns for finite element modeling to check and optimize. Finally, the suggestions of joint optimization design were put forward.

Keywords:cable-membrane structure; static and stability analysis; typical joint; finite element analysis; optimization design
