Abstract

Based on the extreme value of the primary loads of ship hull girder instead of characteristic values, the more reasonable load combination factors are defined. In order to evaluate the random variation of newly defined load combination factors, based on Ferry-Berges & Castanheta (FBC) and Poisson square wave models, the still water bending moments (SWBM), vertical wave bending moments (VWBM) and their combined processes are simulated to get the random realizations of load combination factors. The statistical analysis results show that the load combination factors take the value of 1 with the highest probability and can be well fitted by the Weibull distribution. Such information should be incorporated appropriately in the reliability analysis of ship hull girder.
静水和波浪弯矩的随机组合因子
以船体主梁一次荷载的极值代替特征值,确定了较为合理的荷载组合因子。为了评价新定义的荷载组合因子的随机变化,基于Ferry-Berges & Castanheta (FBC)和泊松方波模型,对静水弯矩(SWBM)、纵波弯矩(VWBM)及其组合过程进行了模拟,得到荷载组合因子的随机实现。统计分析结果表明,载荷组合因子取1的概率最大,能很好地用威布尔分布进行拟合。在船体梁的可靠性分析中,应适当地纳入这些信息。
