钢筋混凝土框架结构三维弹塑性地震反应分析

A 3D elastoplastic seismic responseanalysis of reinforced concrete frame structure

以分段变刚度单元刚度矩阵为基础，采用空间三维分析模型编制了空间弹塑性地震反应时程分析程序，并对实际震害结构进行了分析。

Based on the element stiffness matrix with varied stiffness in different regions, a timehistory analysis programme is developed for elastoplastic seismic response, using 3D analysis model. The accuracy of the method and reliability of the programme are demonstrated by the analysis of an actual seismic damage structure.
