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。
Suqian City Sucheng Culture and Sports Center consists of gymnasium, youth activity center and exhibition hall composed of comprehensive hall, auditorium and cultural center tower. This paper introduces the selection of structural system, the control of calculation index, the design of cross roof trusses and roof connecting streamers in high earthquake intensity, and analyzes the elasticity of the tower, plastic analysis and energy beam section calculation. Basement large open roof for moderate earthquake stress analysis. The calculation results show that the selected structural system is reasonable, safe and reliable, the energy beam section can meet the energy consumption requirements of medium and large earthquakes, and the basement roof can achieve the moderate elasticity.
