RELIABILITY ANALYSIS IN SHIP'S LONGITUDINAL STRENGTH

With the development of shipbuilding theory, structural reliability is becoming an increasingly important subject in ship hull structural design. In this paper, the structural reliability approach is applied to ship longitudinal strength on the basis of analyses of uncertainties of loads and strength. Fully probabilistic method, mean value first order second moment method, advanced first order second moment method and partial factors method are used to yield the general law of safety level of ships by the probability of failure, reliability index and partial factors. The application of these methods on four ships are illustrated as a preliminary investigation, in which two long-term wave load distributions are presented. By discussing the influences of ship velocity, still water bending moment, wave induced bending moment and resistive strength, the key points of our future work is suggested.
