| Research Abstract |
In order to construct the design method of structure supported by piles considered with nonlinear soil-structure interaction, we analytically and experimentally study the influence of the nonlinearity of pile damage on building response. The following conclusions were obtained : (1) The reduction of predominant frequency is mainly caused by the nonlinearity of the soil around piles. (2) The nonlinearity of pile damage has a very small effect in the building response in aftershock. (3) The behavior of piles in inelastic state can be explained in terms of the seismic deformation method
