MODELING OF INELASTIC SOIL-PILE-FOUNDATION INTERACTION SYSTEM

Effects of dynamic interaction to the soil-structure system have been discussed by many researchers and aseismic design procedures taking into account the interaction effects are strongly expected. In this study, we try to incorporate the effects of the dynamic soil-structure interaction can be adapted briefly in the simple Sway-Rocking model. The procedure to evaluate the sway and rocking springs, however, has not been well established yet. We here propose the method to evaluate the soil springs of the soil-pile interaction by using pushover analysis. The results are compared with those of the finite element analysis and both are in good agreement.
