摘要: 提出了利用承载力曲线的响应点判定抗震性能的简易方法. 该方法无需进行地震时程反应分析,只利用传统的静力计算结果,判定抗震性能. 同时还验证了 JSCA 抗震性能篇“简易法”判定标准的合理性.

Abstract:Simplified procedure of seismic performance evaluation is proposed using spectral responses by capacity spectrummethod. It need not perform iterative calculations and makes use of results of static analyses obtained in conventional designprocedure. Also, the validity of the criteria proposed in JSCA Seismic Performance Design Guideline “simplified method”is verified by capacity spectrum method.
