Vibration of rectangular orthotropic plates on elastic half-space

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.
