Abstract

Based on the research of failure mechanism of structure subjected to fixed and fatigue load, ship structural system reliability model is established considering fatigue strength coupling. For the problem of large amount of calculation of searching main failure mode by using advanced branch-and bound method, incremental time method is proposed. The bearing damage ratio and bearing force ratio parameter are put forward, and the units, which can be combined to generate the system main failure mode, are found out with the criteria of minimum increment of time. This method can be a theoretical reference for a quick reasonable assessment of ship structural system reliability.
