[摘要]运用基于性能的抗震设计方法,针对沈阳嘉里中心超限高层结构进行了设计。采用多种程序对结构进行了小震作用下的反应谱分析和动力时程补充计算及中震弹性及不屈服复核,并进行了大震作用下的静力弹塑性分析,且对重要受力构件进行了局部受力分析。结果表明,结构抗震性能良好,体系安全可行。最后结合工程具体抗震设计性能目标,详细提出了拟采用的加强措施,为类似的工程设计提供参考。

Abstract: Based on the performance-based seismic design method, an out-of-code high-rise building of Kerry Centre in Shenyang was designed. Different programs were used to carry out response spectrum calculation and dynamic time-history analysis under the frequent earthquake, elastic analysis and unyielding calculation under the intermediate earthquake, pushover analysis under the rare earthquake, and local stress analysis of important components. The results show that the seismic performance of the structure is well and the structure is safe and reliable. At last, combined with the performance-based seismic design objectives of the project, detailed strengthening measures were put forward to provide reference for similar engineering design.
Keywords: out-of-code high-rise building; performance-based seismic design; seismic strengthening measure; steel reinforced concrete frame-support column; steel reinforced concrete transfer beam
