[摘要] 江蘇省五臺(tái)山體育中心體育館采用鋼網(wǎng)架屋蓋和底部看臺(tái)為混凝土框架的結(jié)構(gòu)。在原結(jié)構(gòu)設(shè)計(jì)時(shí)未進(jìn)行抗震設(shè)計(jì)，根據(jù)原結(jié)構(gòu)設(shè)計(jì)圖紙和檢測(cè)結(jié)果，通過(guò)振型分解反應(yīng)譜法和時(shí)程分析法對(duì)結(jié)構(gòu)進(jìn)行了整體抗震性能分析。分析結(jié)果表明，原結(jié)構(gòu)滿足抗震變形要求，但是部分構(gòu)件承載力不足且構(gòu)造措施不滿足現(xiàn)行規(guī)范要求，整體抗震性能不足，需采取加固改造措施。

Abstract: 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.
Keywords: grid structure;  stand structure;  time history analysis;  seismic performance
