| 摘 要： | 文中对独立柱,独立柱柱顶加连梁两种隔震建筑下部结构设计方案进行了比较。采用ABAQUS非线性有限元分析软件对这两种结构形式进行实体建模。在初始水平力作用下,计算两种结构形式在竖向荷载作用时的轴向承载力。通过竖向荷载-水平位移曲线对两种隔震建筑下部结构设计方案进行定量对比分析,并判断其破坏形式。

| Abstract: | Single column and single column plus link beam design options of isolated building are compared in this paper.Two kinds of structure models are built based on ABAQUS nonlinear finite element software.Axial capacity value of two kinds of structure are calculated with the vertical load as the function of initial shear force.The designs of substructure of two kinds of isolated buildings are compared quantitatively through curves of axial force-horizontal displacement at the same time and we obtained the destruct mode. |
