Transfinite Structure Design of a Sports Center

盐城市体育中心综合馆位于盐城市解放南路体育中心东南角,结构采用框架-抗震墙结构,观众大厅屋面采用钢桁架结构,其余部分采用现浇钢混结构。论文采用PMSAP以及SAP2000对其进行对比分析,同时用Midas Gen对中震下楼板应力、温度应力以及楼板舒适度等进行研究分析。结果表明,所采用的结构方案可以基本满足各性能水准目标,结构方案安全可行。

Yancheng Sports Center complex is located in the southeast corner of Yancheng Jiefang South Road Sports Center, which adopts frame-shear-wall structure. The roof adopts reinforced-concrete structure except for the audience hall which adopts steel-truss structure. In this paper, PMSAP and SAP2000 are used for comparative analysis, and Midas Gen is used to study and analyze the floor stress, temperature stress and floor comfort under moderate earthquake. The analysis results show that the selected structural scheme can basically meet the objectives of each performance level, and the structural scheme is safe and feasible.
