摘 要: | 本文对某一万箱级和某两万箱级的2型超大型集装箱船的极限承载能力分布、静水弯矩分布、波浪弯矩极值预报以及UR S11A要求的极限强度进行了分析,采用改进的一次二阶矩法(FORM),对2型船的失效概率进行计算,旨在验证满足UR S11A极限强度要求的超大型集装箱船的安全水平,以验证此强度准则的可靠性。

Research in Reliability of Ultimate Strength Assessment of VLCS |
| |
Abstract: | In this paper, the distribution of ultimate capacity, still water bending moment, wave bending moment as well as ultimate strength analysis based on UR S11A for 2 sets of VLCS, around 10k and 20k TEU respectively, were carried out. With advanced first order reliability method, failure probability of 2 sets of VLCS has been evaluated, in order to verify the safety level of UR S11A ultimate strength requirement. |
