摘要
针对船舶总纵极限强度极限状态方程不能以显式表达的实际情况,提出采用响应面与映射变换相结合的方法展开船舶总纵强度可靠性分析,指出相关随机变量在正态化前后相关系数的差异应予以考虑,并应用于实际船舶的计算,验证了理论的合理性。
On the basis of review of reliability analysis methods, an approach combining response surface and reflection transformation method is suggested to analyze ship hull girder strength with respect to implicitly expressed ultimate state function, and it is pointed out that the difference between pre and post normalization of random variables should be taken into account. A real ship calculation testifies theory＇s reasonableness.
