in this paper, a three-dimensional base isolated multistory frame structure model is made by the large general structure analysis software ansys.
运用大型有限元软件ansys对某多层框架基础隔震结构建立三维有限元模型。
the lateral deformation of multistory frame structure may mainly be shearing displacement between stories, and shearing model between stories may frequently be adopted in analysis of rigidity matrix.
