| 摘 要： | 在多垂直杆剪力墙单元模型的基础上进行改进,把多垂直杆的轴向刚度和剪切刚度相结合,即每根垂直杆传递轴力的同时还传递剪力,考虑钢材和混凝土损伤累积效应对剪力墙的影响,在上述基础上提出考虑材料损伤累积效应的带暗支撑剪力墙模型,模型更接近带暗支撑剪力墙的受力性能。利用该模型编制的相应程序,对两片分别带有型钢暗支撑和钢筋暗支撑的剪力墙模型进行弹塑性静力加载数值模拟分析,计算结果和试验结果吻合较好,说明方法应用可行。

| Abstract: | The multiple vertical-truss shear wall element model is improved by combining the axial stiffness and the shear stiffness of the multiple vertical-truss wall,so that every vertical truss transfer axial force and shear at the same time,with the steel and concrete cumulative damage effect being taken into consideration.A model of the shear wall with concealed bracings considering material cumulative damage effect is presented,which is similar to the mechanical behavior of the shear wall with concealing bracin... |
