A DYNAMIC ANALYSIS OF UNSYMMETRICAL FRAMEWALL STRUCTURE[J]. Journal of Civil and Environmental Engineering, 1988, 10(4). DOI: 10.11835/j.issn.1674-4764.1988.04.001.
非对称框—剪结构动力分析
摘要
框剪结构是一种使用功能和力学性能兼优的结构。本文将剪力墙视为悬臂薄壁构件;将框架视为多层剪切模型
利用结构矩阵理论推出一系列非对称框剪结构的刚度矩阵公式
然后利用拉格朗日方程得矩阵形式的结构动力方程
最后对一个四十三层非对称框剪结构模型进行动力计算
其结果与实验结果较接近。
Abstract
The frame-wall structure is good both in operational performance and mechanical property. In this paper
the shear-wall is considered as a cantilever thin-wall member
and the frame as a multistoreyed shear model. The theory of structural matrix is used to get a series of stiffness matrix formulas of theunsymmetrical framewall structure. The Largrange equation is used to get dynamic equation of the structure in the form of matrix. At last a 43 storeyed model of unsymmetrical frame-wall structure is calculated
