摘　　要：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。The gymnasium of Jiangshu Wutaishan Sports Center is composed of grid roof structure and stand structure of concrete frame at the bottom.The original structure was designed without seismic design.Based on the design drawing of the original structure and the detection results,this paper analyzes the seismic performance of original structure,according to mode-superposition response spectrum method and time history analysis method.The result of the analysis shows that the deformation of original structure meets the requirements.However,some elements bearing capacity and construction measures don’t meet the requirements of standard.The seismic performance of original structure is insufficient,implying that reinforcement and reconstruction are necessary.
