多肢剪力墙-框架体系在任意水平力作用下的内力和侧移计算

Interal Force and Lateral Deflection Caic6ulation for Multiple Shear Wall-Frame System Acted by Arbitrary Horizontal Loads

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。

Based on the assumption of the continuous distribution of link beam in wall-frame structure, the internal force and lateral deflection equations for the latter under action of horizontal concentrated loads set in arbitrary height are derived and, then, all internal forces and lateral deflections of the structure under loads of any type are determined using the principle of superposition. Also ..all elements of flexibility matrix can be obtained by using above mentioned method when dynamic response is to be calculated by the. vibration mode decomposition and response spectrum method. Different examples are given in this paper. Using presented method, it is pointed out that relative computation error to several other analytical solutions can be limited in any small range,depending on the time increment of superposition.
