框架剪力墙结构简便计算法

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。

A Simple Method for Frame-sheared Wall Structure Calculation

In order to distribute horizontal loads simply and exactly to theframe-sheared wall, and to count on the side-shift, in this article acooperating equation is founded with regard to the frame bending, sheardeformation, bending deformation of the sheared wall, elastic deformationof foundations and other elements. A lot of calculations have been accom-plished on widely applied frame-sheared wall structure with individualload method. A matrix of the cooperating equation and a recursive formulaof the matrix elements are estabeished. These formulas only deal with thenumber of layers, so that the matrix form of any layer's frame-shearedconstruction deformation cooperating equation can be written. The hori-zontal loads can be distributed with computer, substitution of the solutionin shifte expression gives volume of the shift.
