Abstract:The mechanical system of the steel roof of Suzhou Olympic Sports Center Gymnasium is composed of V-shaped columns, rocking columns, top ring trusses and two-way plane trusses. The mechanical system of the structure is clear. The geometric nonlinear global stability analysis of the structure was carried out, and the overall stability safety factor meets the specification requirements. Considering the dynamic effect of key components after failure, the progressive collapse resistance analysis of the steel roof was carried out, and there is not a progressive collapse. The elastic-plastic time-history analysis and key node design of the whole model under the rare earthquakes show that the whole structure and key joints have good mechanical performance.
Keywords:Suzhou Olympics Sports Center; large-span steel structure; rocking column; stability analysis; progressive collapse resistance; elastic-plastic time history; spherical plain bearing
