An Analytical Expression of Motion Equations of SSI System
The soil-structure interaction (SSI) effect is paid more and more attention in the dynamic structural analysis and earthquake resistance protection. However, theoretical analysis of SSI effect cannot accord with engineering applications because the analysis of SSI system is too complicated to be studied with a comprehensive theoretical basis. In order to promote the accuracy of dynamic analysis of SSI system in theory, in this paper, an analytical expression of motion equations of SSI system is given based on the concept of the continuity of dynamic system. In addition, mechanical models of SSI system on the basis of the continuity of motion domains are built and the analytical expression of equations of SSI system is given.
