Efficient derivation of extreme non-Gaussian stochastic structural response using finite-memory nonlinear system. Part 2: model validation

摘要

An analysis of the structure based on linear wave analysis is suggested as a preliminary analysis to assess the overall integrity of the structure. In situations where the results of the preliminary analysis are found to be extreme with several critical conditions, a more detailed structural analysis is suggested to conduct a nonlinear wave. Recently, an efficient model has been developed to test the extreme offshore structural response based on the nonlinear wave analysis using the time-domain approach. It is the derivation of non-Gaussian stochastic offshore structural response using the finite-memory nonlinear system, known as FMNSNL . This paper focuses on the validation on the performance of the FMNSNL method in the analysis of short-term 100-year of extreme offshore structural responses. Providing good accuracy, the FMNSNL method offered a more efficient approach for an optimum and economical structural analysis.
