| 摘 要： | 利用有限元方法对单立柱海洋平台在波浪等环境荷载作用下进行响应分析,以此为基础对其进行构件和体系两个层次的可靠度分析。构件可靠度分析采用Monte-Carlo方法,考虑了多元失效模式,建立了四种功能函数,分别得到每个构件失效概率的区间估计。把单立柱平台作为串连系统来考虑,从而求得体系可靠概率的区间估计。并对影响构件可靠性的因素进行了敏感性分析。

| Abstract: | Based on finite element method response analysis on a single-leg jacket platform is performed under environmental loading.Both analyse on member reliability and system reliability are accomplished on the base of the above FEM Results.Monte-Carlo method considering four failure modes is used on member reliability analysis.The range of failure probability for each member is obtained.The range of system reliability considering the platform as series mode is achieved.Sensitivity analysis is presented to study the influential factors on member reliability. |
