摘要
本文在剪力墙-框架结构连系梁连续化假设的基础上,推导了任意标高处具有水平集中力作用的多肢剪力墙-框架体系连系梁内力及结构侧移的解析公式,进而利用迭加原理求解任意荷载形式下结构的内力和侧移。这一方法也适用于求采用振型分解法计算结构动力响应时所需的柔度矩阵系数。文中列举了不同情况的算例。随着迭加次数的增大,采用本文方法所得的结果与几种解析解的相对误差可控制在任意小的范围之内。
On the basis of the assumption that the link beam in the wall-frame struc-ture is a continuum, equations for the calculation of internal force of the linkbeam and lateral drift of the structure under action of horizontal concentratedloads at any height are proposed in this paper. Moreover, all forces and lateraldeflections of a structure under any kind of loads are determined, based on theprinciple of superposition. Also, all elements in a flexibility matrix can be ob-tained by the above-mentioned method when dynamic response is calculated bythe vibration mode decomposition and response spectrum method.Three examplesare given in order to prove the advantage of the present method. It is pointed outthat the relative error of this method when compared with the other analyticalsolutions can be limited in a small range, depending on the time increment ofsuperposition.
