摘要
本文分析了国际船级社协会（IACS）纵向强度标准S11中，波浪弯矩设计值与在采用IACSWP／S委员会推荐的海浪谱和海况统计资料条件下的长期预报理论计算值的关系，大量计算实践表明后者总体上要比前者大1．5倍。文中建议为了把长期预报技术应用于船体波浪弯矩的直接设计计算，对上述预报过程可取10-5.5概率水平时的长期预报值作为船体波浪弯矩设计值。
This paper analyses the relationship between the design values of wave-induced bend ing moments according to the IACS UR S11 and the value of long-term prediction using the IACS standard wave spectrum and wave data. In general the results of a large amount of calculation indicate that the later is more than 1. 5 timeslarger. And finally this paper suggests that taking the long-term prediction with probability level 10-5.5 is suitable for design value of the wave-induced bending moments in the direct design calculation.
