摘要
基于作者提出的结构余度概率衡准，并通过对船体构件损伤模型与船体总纵强度可靠性计算模型的讨论，本文建立了一个合理而简便的受损船体总纵剩余强度预报方法。根据本文提出的方法对某实船在不司损伤情况下的总纵剩余强度进行了预报，并得到了一些有意义的结论。
A rational method based on the concept of structural redundancy and reliability analysis is presented in this paper to estimate the residual longitudinal strength of damaged ship hull. Emphasis is given to the definition of a new probabilistic measure of structural redundancy. Semi-analytical calculation models of damaged structural members with initial elasto-plastic distortion are briefly discussed. And finally, a numerical example is implemented and some conclusions have been drawn.
