摘要
进行船体总纵极限强度的可靠性计算包括4个方面:①失效模式;②总纵极限强度;③外载荷;④可靠性分析方法.采用基于条件期望技术和对偶变数技术的Monte-Carlo法对船体进行总纵极限强度可靠性计算.
Reliability analysis for ultimate strength of ship hull girder requires consideration of the following four aspects:(1) failure function; (2) ultimate strength; (3) loads; (4) method of reliability analysis. A modified Monte Carlo method combined with variance reduction techniques(VRT) of conditional expectation(CE) and antithetic variates(AV) was adopted to calculate the failure probability of ship hull girder. An example was analysed to verify the efficiency and rationality of the proposed method.
