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。 In this paper, the elasto-plastic dynamic analysis method and programming techniques for high-rise and complex structure space are introduced. The programmed EPDA program absorbs the advantages of the high-level structure spatial cooperative elastic dynamic analysis program FW05 and the planar rod elastic-plastic dynamic analysis program NDRAIN. Finally, the analysis results of a reinforced concrete structure with a split layer under multi-dimensional time history are given.
