| Abstract: | A comprehensive and system method is proposed in this paper to analyse the reliabili ty of longitudinal strength of composite ship structures. Various uncertainties of struc tures and environmental loads are considered and important failure modes are developed. Response Surface (RS) method is applied to calculating the probabilities of failure modes.A numerical example, the structural reliability analysis of a single skin GRP boat, is car ried out. The obtained conclusions are valuable for designing reasonable and effective com posite vessels. |
