摘要
利用在剪力墙多垂直杆非线性单元模型中增设支撑斜杆的方法,来分析带暗支撑剪力墙结构的非线性地震反应,给出了带支撑斜杆的多垂直杆剪力墙单元模型的刚度矩阵和各元件的本构关系。最后提供了算例,并与试验结果比较,表明带支撑斜杆的多垂直杆剪力墙非线性单元模型具有较好的计算精度。
In this paper, a nonlinear element model with parallel and oblique multi-component for shear wall with concealing bracings is proposed.The derivation process of the element stiffness matrix and the constitutive relations for all the constituent components are provided. Finally,two examples are calculated and compared with test results, which show that the model tests are accurate.
