| Abstract: | The method of double Fourier transform has been introduced for the analysis of rectangular foundation loaded with vertical steady vibrations on an elastic half space. And an integral representation for displacements and dynamic stiffness of rectangular foundation was presented. From the numerical evaluation and investigation ,the effects of Poisson ratio and shape of foundation on dynamic stiffness were discussed,which is important for the analysis of the dynamic interaction of soil-structure and machine foundation. |

| Keywords: | elastic half-space steady vibration dynamic stiffness |
