This paper presents a methodology to assess the reliability against collapse of structural members, as typified by the buckling collapse of stiffened deck panels in ship structures. This methodology uses tools for evaluation of the limit states, modeling of loads, geometry and material properties, reliability assessment and sensitivity analysis. The proposed methodology estimates the failure probabilities of the above failure mode and determine the most important uncertainties using sensitivity analysis. The methodology is illustrated by analyzing the reliability of a cruiser.
