| 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, the result is close to the test. |
