| 摘 要： | 建立了适合于带暗支撑短肢剪力墙非线性分析的宏观计算模型，分析推导了SAP程序中Link单元的刚度矩阵，明确了Link（单元中各弹簧的物理意义，给出了各单元等效刚度计算方法，选取了合适的单元力一位移关系。用由Link单元建立的宏观模型对3片普通短肢剪力墙和3片带暗支撑短肢剪力墙进行了静力弹塑性分析，试验和计算所得顶点力一位移骨架曲线符合良好，说明所建宏观模型合理，用由Link单元建立的宏观模型能较好的模拟带暗支撑短肢剪力墙的非线性行为。

| Abstract: | A macroscopic calculating model is put forward to analyze short limb shear wall with concealed bracings. The stiffness matrix of Link element in SAP2000 is deduced and the defining method of linear effective stiffness is developed. The reasonable force-displacement relationship for the Link element is selected. Push over analysis using the macroscopic model composed with Link element on short limb shear walls with and without concealed bracings is carried out. The calculated top force-displacement curves agree well with that of experiments,which indicate that the macroscopic model is reasonable. |
