摘　　要：苏州奥体中心体育馆钢屋盖受力体系由V形柱、摇摆柱、顶部环桁架和双向平面桁架组成,结构受力体系清晰。对结构进行了几何非线性整体稳定分析,整体稳定安全系数满足规范要求。考虑关键构件破坏后的动力效应,对钢屋盖进行了抗连续倒塌分析,结构不会出现连续倒塌。整体模型罕遇地震弹塑性时程分析和关键节点设计显示,整体结构和关键节点具有良好的受力性能。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.
