Based on the secondary development of LS-DYNA program, the nonlinear dynamic p-y model and Bonora damage material model of steel were applied in the main program. Taking a four-span approach bridge as an example, the plastic damage model of the upper bridge and four simplified bridge pile-foundation models, including beam on Winkler foundation model, effective length pile model, total pile model considering soil-structure interaction (SSI) and no pile model, were introduced. The earthquake motions obtained by a free-field analysis were applied to the different depth of pile profile. The free vibration characteristics, displacement, internal force and damage under different levels of earthquake motions were analyzed. The stress-strain curve of different depth of p-y elements and pile deflection of Winkler-methods model were discussed. Analysis results indicated that the structure responses are different among the four pile-foundation models, the responses of the bridge in longitudinal and transverse directions are totally different, and the p-y model can be used to simulate the bridge precisely.
