Nonlinear Dynamic Analysis of Pile Foundation Embedded in Sand Subjected to Strong Ground Motion Using Fiber Elements

In this paper Fiber Element is used for modeling soil–pile interaction during earthquakes. In this model, both pile and surrounding soil are modeled using fiber elements. This model is developed using DRAIN–3DX software. In this method, behavior of soil is assign to fiber elements using p-y curves. In order to consider effects of free field soil on the motion, EERA and NERA software are used. In this paper pile behavior embedded in sandy soil subjected to strong ground motion were analyzed and compared with available experimental results. The model can be used for soil – pile – structure interaction analysis of jacket type offshore structure.© 2006 ASME
