The response of pile supported fixed offshore jackets is very sensitive under earthquake loadings. These structures shall be able to undergo the seismic loadings without any failure. To reach this purposes the dynamic analysis should be considered because of some factors like soil nonlinearity, energy dissipation, nonlinear behavior of foundations, discontinuity condition at pile soil interfaces and etc. the noticeable part of dynamic response of fixed offshore jackets is nonlinear behavior of piles. In this paper, innovative and newest approaches in nonlinear analysis together with ABAQUS modeling to be used to extract the useful conclusions related to dynamic nonlinear response of fixed offshore jackets.
