江苏省五台山体育中心体育馆采用钢网架屋盖和底部看台为混凝土框架的结构。在原结构设计时未进行抗震设计,根据原结构设计图纸和检测结果,通过振型分解反应谱法和时程分析法对结构进行了整体抗震性能分析。分析结果表明,原结构满足抗震变形要求,但是部分构件承载力不足且构造措施不满足现行规范要求,整体抗震性能不足,需采取加固改造措施。
Sports Center, Wutai Mountain, Jiangsu Province, gymnasium with steel grid roof and the bottom of the stands for the concrete frame structure. In the original design of the structure without seismic design, according to the original structure design drawings and test results, the vibration mode decomposition response spectrum method and the time-history analysis of the structure of the overall seismic performance. The analysis results show that the original structure meets the requirements of seismic deformation. However, some of the components have insufficient bearing capacity and the structural measures do not meet the requirements of the current codes. Therefore, the overall seismic performance is not sufficient and the reinforcement and reconstruction measures should be taken.
