摘　　要：框架－剪力墙结构是一种较好的抗震结构体系。为验算这类结构在强烈地震作用下的弹塑性变形性能，需开发简便实用的分析方法和软件。本文用框架门型单元和墙四弹簧单元结合进行高层框－剪结构空间协同／平面弹塑性地震反应分析。这两种单元结合，可较好地反映框－剪结构在地震作用下的动力性能，且模型相对简单，计算时间少，具有较高的实用性。rame-wall structures may proyide significant resistance against earthquake action. For a check of the global dynamdc performance of such structures, there is a need fbr sim- ple and efficient analytical methods and computational software. In this paper, door-like elements for frame and four-spring elements for wall are used for elasto - plastic seismic response analysis of frame-wall structures. By combining these two kinds of elements, the dynamic characteristics of fYazne-wall structures under seismic ac- tion can be retlected well. This method can decrease oomputational time and so has high practicability.
