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 for calculating floor stiffness ratio are introduced. Through the analysis and comparison of the elasto-plastic time-history of the four schemes under the earthquake with frequent earthquake and the rare earthquake, the lateral stiffness of the frame structure is irregular Discrimination method for discussion, for the revision of norms and design reference.
