摘　　要：提出了底部两层框架剪力墙砖房这类上下混合承重结构体系的空间协同弹塑性地震反应时程分析方法。假定楼板为分区刚性，对上部砌体结构进行了空间剪扭分析，并引入了砖墙的滞回特性；对下部框剪结构采用带刚域的杆单元，并引入了墙板单元。可沿任意角度输入相互垂直的两个水平地震动分量，并且采用了改进的Ｗｉｌｓｏｎ－θ法。针对一个工程实例，应用本文方法进行了弹塑性动力分析。おy introducing the hysteretic behavior of masonry and using the assumption that the floor is infinitely rigid in different areas,a method is presented for analysis of nonlinear seismic responses of masonry with R/C frame-wall in the first and the second floors.The propagation direction of earthquake excitation is considered.A modified wilson-θ method is proposed and a microcomputer-based program of nonlinear dynamic analysis of this kind building is developed.
