| 摘 要： | 研究短肢剪力墙的力学模型和计算方法,根据T形短肢剪力墙的受力和变形特点,提出一种10自由度的变形杆系广义墙元模型。考虑翼缘墙与腹板墙的空间耦合作用,运用虚功原理建立T形短肢剪力墙的单元刚度矩阵。为短肢剪力墙结构空间弹塑性分析提供了新的思路,这一宏模型摒弃了现有宏模型中平面假定的限制,不仅可以反映中和轴的移动,而且还可以反映初始截面的剪切翘曲,并且编制了弹塑性时程分析程序,并输入三种不同的地震动进行了算例分析。

| Abstract: | The mechanical models and calculation methods of a short-leg shear wall are researched.According to the mechanical and deformation properties of a T-shaped short-leg shear wall,a generalized wall element model for deformed bars with ten degrees of freedom is put forward.Then the stiffness matrix of the T-shaped short-leg shear wall is derived by means of the virtual work principle,and the conceptual design is provided to the elastoplastic analysis on structure of the short-leg shear wall.This scheme reflect... |
