摘 要:近场地震具有的长周期速度脉冲会显著改变结构的响应,使结构在瞬间产生较大的侧移。用屈服点谱(YPS)法对两个中心支撑钢框架算例进行了抗震性态评估,并将得出的结构峰值位移和层间位移角与非线性时程分析的结果进行了比较,评价了YPS法结构抗震评估的精度。A long period velocity pulse in the near-fault earthquake can dramatically change the structure's re sponse, leading to the momentary lateral movement of the structure. YPS is used to estimate the peak displace-ment and interstory drift indices (IDI) of the two inverted-V concentrically braced steel frames, and a contrast is made between the peak displacement of the structure and IDI estimated by YPS method with the results estimat-ed by time-history analysis. Finally, the paper evaluates the credibility of YPS method applied to seismic evalua- tion.
