【Abstract】 A detailed description of the actual development of finite element model of R-C frame is provided in this paper. The elastic-plastic element stiffness matrix is proposed. The elastic-plastic seismic response of R-C frame is calculated in detail using space-cooperation method and the program for calculating the dynamic characteristic, the elastic seismic response and the elastic-plastic seismic response is compiled.更多还原
