摘　　要：本文介绍了高层及复杂结构空间协同弹塑性动力分析方法及编程技巧,所编制的程序EPDA吸收了高层结构空间协同弹性动力分析程序FW05与平面杆系弹塑性动力分析程序NDRAIN两者的优点。最后给出了一个具有错层的钢筋砼结构在多维时程下的分析结果。A method of elasto-plastic dynamic analysis for multistory and complex structures through space interaction of two-dimensional substructures at multi-dimensional ground accelerations as well as the programming skills are presented in this paper. The presented program takes advantage of program FWo5 and NDRAIN, the former being an elastic dynamic analysis program for multistory structures by space interaction and the latter an elasto-plastic dynamic analysis program for plane structures. The program can be used for structural designs.The analytical results of a RC structure subjected to multi-dimensional ground accelerations are also given in the paper.
