摘要
介绍了关于楼层刚度比计算的三种方法,通过对四个方案在多遇地震作用下的抗震验算和罕遇地震作用下的弹塑性时程分析、比较,对框架结构楼层侧向刚度不规则判别方法进行讨论,可供修订规范及设计时参考。
Three methods of calculating the lateral stiffness ratio of adjacent story are introduced. By comparing the results of seismic check of frequently occurred earthquake and elastic-plastic time history analysis of rarely occurred earthquake of four projects, the method of judging the lateral stiffness of the frame structure is proposed, which can be offered to the revision of relevant design code for reference.
