摘要
在总结钢筋混凝土框架结构其各种计算模型的基础上 ,推导了单杆件的弹塑性刚度矩阵 ,并采用空间协同分析的方法对框架结构在地震作用下的弹塑性响应进行了计算和分析 ,开发了计算框架结构动力特性、框架结构在地震作用下弹性响应。
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.
