摘要
本文基于国内外非线性静力分析方法，阐述了最近由Chopra和Goel提出的改进能力谱法的基本概念和实施步骤；其次，结合文献[18]中提出的钢筋混凝土结构地震损伤“三水准”性能目标和改进能力谱法，提出了基于能力谱法的结构地震损伤性能简化设计及验算方法；最后，通过设计例题说明了本文方法的可行性，并将计算结果与时程分析进行了比较，显示了此法的有效性。
In this paper, based on the nonlinear static analysis method at home and abroad,the fundamental concepts and implementing procedure of improved capacity spectrum method recently developed by Chopra and Goel are introduced firstly. Secondly, on the basis of this method and three-level seismic damage performance objectives suggested in reference[18] for reinforced concrete structures, a simplified design and checking method of structural seisAnc damage performance is put forward. Finally, the feasibility of the method is verified through an example. And the validity of this method is also shown by making a comparison between computation results of the method and time-history analysis.
