摘要

本文针对异形柱结构抗震性能的评估,运用模态pushover以及等强度延性需求谱的方法,对等效的单自由度体系进行计算,得出其相应的延性系数及位移后,再转化为多自由度体系的位移需求。并对两个异形柱结构算例进行抗震性能分析,可供异形柱结构抗震性能研究和评估参考应用。
Based on the seismic performance evaluation of the structure with specially shaped columns and using modal pushover and constant-strength ductility demand spectrum method,the equivalent single degree of freedom system was calculated.Then the corresponding ductility factor and displacement were obtained and transformed into the displacement requirement of multi-degree of freedom.The seismic performance evaluation of two actural structures with specially shaped columns system was conducted,the result could be referred by the study and evaluation of seismic behavior of structure with specially shaped columns.
