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 $\mathrm{F}\mathrm{M}\mathrm{N}{\mathrm{S}}_{\mathrm{N}\mathrm{L}}$. This paper focuses on the validation on the performance of the $\mathrm{F}\mathrm{M}\mathrm{N}{\mathrm{S}}_{\mathrm{N}\mathrm{L}}$ method in the analysis of short-term 100-year of extreme offshore structural responses. Providing good accuracy, the $\mathrm{F}\mathrm{M}\mathrm{N}{\mathrm{S}}_{\mathrm{N}\mathrm{L}}$ method offered a more efficient approach for an optimum and economical structural analysis.

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$\mathrm{F}\mathrm{米}\mathrm{ñ}{\mathrm{小号}}_{\mathrm{ñ}\mathrm{大号}}$. 本文着重于对性能的验证$\mathrm{F}\mathrm{米}\mathrm{ñ}{\mathrm{小号}}_{\mathrm{ñ}\mathrm{大号}}$短期 100 年极端海上结构响应分析方法。提供良好的准确性，$\mathrm{F}\mathrm{米}\mathrm{ñ}{\mathrm{小号}}_{\mathrm{ñ}\mathrm{大号}}$方法为优化和经济的结构分析提供了一种更有效的方法。
