| 摘 要： | 通过对短肢剪力墙受力分析的研究，考虑了翼板的“剪力滞后”效应，构造了新的纵向位移函数，利用能量变分原理导出了考虑剪滞效应和剪切变形的控制方程和边界条件，并以控制方程的解析解为形函数，利用边界条件和刚度法建立了异形截面短肢剪力墙的统一单元刚度矩阵，并利用空间变换原理建立了空间分析刚度矩阵。通过算例并和其它分析模型比较，结果表明本方法能求得较满意的结果。

| Abstract: | Static analyses of short-leg shear wall are investigated. According to the variational principle, the governing equations and boundary conditions for the elastic analysis of the short-leg shear wall are derived by introducing a new cross displacement function which considers the effect of shear-lag and shear deformation. Based on the boundary conditions and stiffness method, the integrated element stiffness matrix is developed, and the spatial stiffness matrix is proposed by spatial transformation.Finally an example is calculated, the results obtained are compared with those of other analytic model ,which shows that the model has fairly good accuracy. |
