Pile-Soil-Structure Interaction (PSSI) can significantly affect the seismic performance of structures. The pile-soil interaction during earthquake loading is one of the most important sources of nonlinearity of offshore platforms. Incremental Dynamic Analysis (IDA) is an emerging analysis method that offers thorough seismic demand and capacity prediction capability. This involves performing a series of nonlinear time history analyses under a suite of ground motion records by equally scaling both components of each record to several levels of intensity and recording the structural response. This paper presents an efficient method to specify the effect of Seismic Soil-Pile-Structure Interaction (SSPSI) on structure through IDA method and shows suitable length to model offshore with equivalent dummy piles for more accuracy. Three-dimensional finite element model of offshore, jacket with both equivalent dummy piles (pile stub) and true piles considering soil-pile-structure interaction are subjected to Incremental Dynamic Analysis and the results of both are compared in terms of IDA curves. In this paper, a computer program for Nonlinear Earthquake site Response Analyses of layered soil deposits (NERA) is used for nonlinear response of soil layers. Modeling of structure of offshore with its pile is performed with a FEM program (OpenSees) considering the effects of pile-soil-structure interaction using p-y curves.
