000009434 520__ $$2eng$$aThe exploitation for offshore oil has become increasingly widespread in the past decades. Steel offshore platforms are commonly constructed to accommodate operation facilities and to withstand environmental and accidental loads during oil exploitation operation. Particular attention is being paid to earthquake loads in seismic active areas because it directly influences the performance of the offshore structure installations. Incremental Dynamic Analysis (IDA) is a powerful tool to assess the capacity of a structure subjected to seismic loads. In this paper, IDA analysis is performed on a newly designed and installed offshore platform through the use of nonlinear finite element program. Pile-soil interaction and post-buckling of lateral load resisting elements are considered and relevant demand parameters are introduced. Nonlinear pile model is used to capture the failure of piles so that the capacity and demand of the structure can be estimated more accurately. It is concluded that using different demand parameters may change the summarized IDA curves especially in highly nonlinear responses of the structure.
