摘要
利用fortran编写了显式积分中的中心差分法,并根据一高层框架剪力墙结构的简化模型进行分析.根据结构的不同刚度值分别在弹性和弹塑性阶段得出结构的位移数据.做出数据曲线,查看其敛散性,并与WILSON-θ法进行对比分析结构的性能对显式积分的影响.
The central difference method of the explicit integration was compiled based on Fortran language and a simplified model of the Frame shear wall structure was analyzed. According to the different stiffness values of the structure, the structure displacement data were obtained in the elastic and elastoplastie phases. And the data curve was worked out. Its convergence and divergence viewed. The impact of the structure capability on the explicit integration was compared with that by WILSON0 method.
