两个广义位移梁理论在框—剪结构自由振动中的应用

Applicaion of Theory of the Beam with Two Generalized Displacements to the Free Vibration of Frame-Shear Wall Structnres

本文应用具有两个广义位移的梁理论,推导了框架一剪力墙结构考虑剪力墙的剪切变形及截面转动惯量的自由振动微分方程,求得了相应的频率方程和振型函数.文中附有算例.

In this paper, the free vibration differential equations of frame-shear wall structures are derived with the help of the theory of the beam with two genralized displacements, and the frequency equations and mode functions are obtained. In the derivation, the effects of transverse-shear deformation and rotatory inertia of the shear wall are taken into account. A numerical example is also given.
