ABSTRACT

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.

使用有限记忆非线性系统有效推导极端非高斯随机结构响应。第 2 部分:模型验证

摘要

建议基于线性波分析对结构进行分析,作为评估结构整体完整性的初步分析。在初步分析的结果发现在几个临界条件下极端的情况下,建议进行更详细的结构分析以进行非线性波。最近,基于非线性波浪分析,使用时域方法开发了一种有效的模型来测试极端海上结构响应。它是使用有限记忆非线性系统推导非高斯随机海上结构响应,称为Fñ小号ñ大号. 本文着重于对性能的验证Fñ小号ñ大号短期 100 年极端海上结构响应分析方法。提供良好的准确性,Fñ小号ñ大号方法为优化和经济的结构分析提供了一种更有效的方法。
