为了简便而准确地将水平荷载分配给框架和剪力墙,并计算出水平侧移,本文中考虑框架弯、剪型弯形和剪力墙弯曲型变形,且又考虑地基弹性变形等因素而建立起变形协调方程。用单位荷载法对实际设计中用得最广的框架剪力墙结构做了大量的计算工作,得出了协调方程的矩阵形式,进一步得出矩阵元素的递推公式。这些公式只与结构的层数有关,因此可以写出任意层数的框架剪力墙结构变形协调方程的矩阵形式。用计算机求解即将水平荷载分配完毕,将此解代入位移表达式即算出位移值。
In order to simply and accurately distribute the horizontal load to the frame and shear wall and calculate the horizontal lateral displacement, this paper considers the bending deformation of the frame bending, shear bending and shear wall, and considers the elastic deformation of the foundation and other factors. Set up the deformation coordination equation. The unit load method was used to do a lot of calculation work on the frame shear wall structure that is used most widely in the actual design. The matrix form of the coordination equation was obtained, and the recurrence formula of the matrix elements was further obtained. These formulas are only related to the number of layers of the structure, so it is possible to write a matrix form of the deformation coordination equation of the frame shear wall structure for any number of layers. The computer is used to solve the problem that the distribution of the horizontal load is completed, and the solution is substituted into the displacement expression to calculate the displacement value.
