框架-剪力墙-薄壁筒斜交结构分析的初参数法

The initial parameter method for analysis of frame-shear wall-thin walled cores cooperating systems

本文通过连续化假定,将框架-剪力墙-薄壁筒斜交结构视为广义空间薄壁剪-弯柱,给出了在水平荷载(含扭矩)作用下广义柱的平衡方程,然后由广义柱正则化后的微分方程分别求出广义柱的矩阵形式的初参数解,由结构顶部和底部的边界条件求出初参数,进而求出结构各构件的内力和位移。本文提出的方法使用的数学工具简单,思路清楚,计算量小,精度高,容易被工程技术人员接受。

In this paper, by use of the continuum technique, the frame-shear wall-thin walled cores cooperating systems with skew plane form are thought of as generalized space thin wall shear-bending columns, the equilibrium equations of the generalized column subject to lateral loads are derived. Then the initial parameter solution expressed in form of matrix are given according to decoupled differential equations of generalized columns, hence the initial parameters can be determined by using boundary conditions of the top and base of the structures, and then the internal forces and deformations of every members are obtained. This method possesses the merit of simple mathematical role, clear train of thought, easy calculation and high accuracy, so it can be accepted easily by engineering technical personnel.
