摘　　要：针对若干有代表性的巨型钢框架结构进行了在强震作用下考虑几何非线性的弹塑性时程反应分析,得到了结构的位移、速度、加速度时程响应,给出了结构各层位移包络值、层间位移包络值和塑性铰出现的位置,并讨论了巨型梁柱、地震波等因素对巨型钢框架结构抗震性能的影响。Considering geometric non-linearity,the inelastic response history analyses of some typical mega steel frames are carried out under strong motion earthquakes.The time histories of displacement,velocity and accelera- tion of the mega steel frame structures are obtained.And also the displacement or relative displacement envelope values of every floor and the appeared positions of plastic hinges for the mega steel frames are presented.At last, the effect of mega members and different earthquake waves to the earthquake resistant behaviour of the mega steel frames are discussed.
