摘　　要：四平市体育馆下部结构采用钢筋混凝土框架结构,比赛馆大跨度屋盖采用钢桁架结构,中央采光天窗区域局部采用索承网壳的混合结构体系。各框架柱的荷载差异较大,采用独立基础与复合桩基两种基础形式,有效地控制了柱间沉降差。针对楼板缺失及薄弱连接,进行楼板应力分析,并根据分析结果对局部楼板有针对性地进行加强。计算采用下部钢筋混凝土结构和钢结构屋盖整体模型,通过罕遇地震作用下的静力弹塑性分析表明,结构可以满足既定的C级性能目标。The substructure of Siping Gymnasium adopts reinforced concrete frame structure,the large-span roof of the competition hall adopts steel truss structure,and the central skylight area locally adopts a hybrid structure system of cable-supported reticulated shell.The load difference among each frame column is large,and two foundation forms of independent foundation and composite pile foundation are used to effectively control the settlement difference among columns.In view of thefloor missing and weak connection,the floor stress analysis is carried out,and the localfloors are strengthened according to the analysis results.The calculation uses the overall model of the lower reinforced concrete structure and the steel structure roof.The static elastoplastic analysis under rare earthquake action shows that the structure can meet the established C-level performance goal.
