宿迁市宿城区文化体育中心结构分析与设计

Structural analysis and design of Sucheng District Cultural and Sports Center in Suqian city

宿迁市宿城区文化体育中心由体育馆、青少年活动中心与展示厅组成的综合馆、演艺厅以及文化馆塔楼组成。介绍了高地震烈度下各单体的结构体系的选择、计算指标的控制、体育馆屋面交叉桁架及屋面连接飘带的设计,并对塔楼进行了弹性分析、塑性分析及耗能梁段的计算,对地下室大开洞顶板进行了中震应力分析。计算结果表明,所选结构体系合理、安全、可靠,耗能梁段满足中、大震耗能需求,地下室顶板可实现中震弹性。

Sucheng District Cultural and Sports Center in Suqian city contains gymnasium,comprehensive gymnasium composed of youth activity center and exhibition hall,auditorium and cultural museum tower. The selection of structural system of each monomer building and the control of calculation indices under high seismic intensity were introduced as well as designs of the cross truss of the gymnasium roof and roof connection ribbon. The elastic analysis,plastic analysis and the calculation of the energy dissipation beam segment of the tower were conducted. The stress analysis on basement roof with big openings under the fortification earthquake was conducted. The results show that the selected structural system is reasonable,safe and reliable,and energy dissipation beam segment meets the energy dissipation requirements under the fortification and rare earthquakes respectively. The basement roof keeps elasticity under the fortification earthquake.
