Abstract: A behavior of a pile supported structure is affected by nonlinear dynamic soil-structure interaction during earthquake. There are two major factors which affect the nonlinear soil-structure interaction, the one is the local nonlinearity and the other is the site nonlinearity. In this paper, the p-y model has been developed by taking into account both of these two effects. The applicability of this p-y model to the site nonlinearity has already been confirmed through the simulation analyses of lateral load tests of full-scale single piles. The simulation analyses are conducted to confirm that the proposed model is useful in the dynamic soil-pile-structure interaction problem. The estimated results by pseudo-static analyses using the proposed p-y model are compared to the results of the bending moment, displacement and shear force in the centrifuge table test and in the shaking table tests. The estimated bending moment, displacement and shear force are good agreement with observed results.
