| 摘 要： | 以反应谱理论为依据,建立了循环侧推的多振型高层建筑结构静力弹塑性分析方法。在此基础上,归纳、总结得到结构等效恢复力模型的骨架曲线及滞回特性,发展了较简单且较为精确的计算在地震作用下高层建筑结构顶层位移反应的方法。探讨了应用静力、动力弹塑性分析结果进行抗震性能评估的基本原则。最后给出算例对本文的研究进行了论证。

| Abstract: | A modified pushover analysis and seismic performance evaluation for tall building are proposed in the paper. It is to be noted that the effects of higher modes under circulating lateral loading are considered. It is based on the response spectrum theory. An effective approach for the restoring force model is then obtained; a simplified approach for the top displacement under earthquake ground motion is put forward. It is found that the seismic performance evaluation of tall building structures is discussed. An example is given using the data of a RC frame-shear wall structure with seven stories. |
