Vibration of rectangular orthotropic plates on elastic half-space

本文基于弹性半空间振动问题的积分变换解,用链杆法分析了弹性半空间上正交各向异性矩形板的振动问题。推导了问题的控制方程组,将弹性半空间地基与正交各向异性矩形板的相互作用问题转化代数方程组的求解问题。文中算例表明,链杆法是用来分析地基与基础振动问题的有效方法。

The effect of soil -structure interaction is recognized to be important and cannot be neg- lected. This paper analyzed the problems of interaction between orthotropic rectangular plates and e- lastic half- space foundation by rigid bar method and based upon the integral transform solution for vibration of the elastic half - space. Through derived the controlling equations, the problems of in- teractions between plate and half - space are changed to the problems of algebraic equations. The numerical results prove that rigid bar method is the effective way of analyzing interactions between plates and foundation.
