BSI振动梁函数在高层建筑中的应用

The Free Vibration of Frame-Shear Wall Structure Including Shear Deformation and Rotatouy Inertia

本文应用具有两个广义位移的梁的理论推导了高层建筑中框架—剪力墙结构考虑剪切变形和截面转动惯量的影响的自由振动微分方程,求得了相应的频率方程和振型函数。(简称 BSI 振动梁函数)文末给出剪力墙和框架—剪力墙结构算例以说明剪切变形及截面转动惯量对结构动力特性的影响。

In this paper,the differential equations of free vibration of the frame— shear wall structure including the effect of shear deformation and of rotatory inertia are derived in accordance with the theory of beam with two generalized displacements. The Corresponding frequency equations and the normal functions are found. The examples of the shear wall and the frame—shear wall given illustrate the effect of shear deformation and of rotatory ineria on the dynamic properties of the structures.
