本文根据Winkler假设,考虑土与剪力墙基础的共同作用,修正框架—剪力墙高层结构挠度形状基本微分方程的边界条件。根据所得的解,确定了包括位移和应力约束在内的约束条件,再根据反应谱理论确定目标函数地震力,最后以剪力墙有效刚度作为设计变量,建立了考虑剪力墙基础转动确定剪力墙最优刚度的数学模型,利用这个模型详细讨论了剪力墙基础转动对剪力墙最优刚度的影响。
Based on the Winkler hypothesis, this paper considers the joint action of soil and shear wall foundations, and corrects the boundary conditions of the deflection-shape basic differential equations of frame-shear wall high-rise structures. According to the solution obtained, the constraints including the displacement and stress constraints are determined. Then the seismic force of the objective function is determined according to the response spectrum theory. Finally, the effective stiffness of the shear wall is used as the design variable, and the shearing wall foundation rotation is adopted to determine the shear. Based on the mathematical model of the optimal stiffness of the wall, this model was used to discuss in detail the influence of the rotation of the shear wall on the optimal stiffness of the shear wall.
