摘　　要：苏州市某文体中心体育场馆共3层,最大跨度达34.5 m。结构荷载及跨度均较大,楼面支撑采用桁架梁。该桁架梁两端支座水平荷载较大,连接柱难以满足承载力要求,考虑设计及施工可行性,文章提出滑动支座设置,分析新支座形式下结构变形、内力及抗震性能,给出的桁架梁滑移支座具体设置方案可供同类工程参考。The gymnasium of a sports center in Suzhou consists of three stores,with a span of 34.5 m.The load and span of the structure are large,and the truss beam is used in the floor support.The horizontal load of the support at both ends of the truss beam is large,and the connecting column is difficult to meet the requirements of bearing capacity.Considering the feasibility of design and construction,the setting of sliding support is put forward,and the structural deformation,internal force and seismic performance under the new support form are analyzed.The specific setting scheme of the sliding bearing of the truss beam is given,which can be used as a reference for similar projects.
