A METHOD FOR RELIABILITY ASSESSMENT OF SPATIAL FRAME STRUCTURES BASED ON ULTIMATE STRENGTH ANALYSIS

This paper is concerned with the reliability assessment of ship main structures, which are modeled as spatial frame structures and subjected to quasi-static extreme loads. It is described how ultimate strength is analyzed to generate safety margins in relation to structural failure. Probabilistically dominant collapse modes are identified by applying the so-called branch-and-bound method combined with heuristic operations. The techniques used are successfully applied to the main structures of a 240,000 dwt tanker under various notational loading conditions. The probabilistic properties of the ultimate strength of ship main structures are investigated through numerical examples and through comparison with previous results for plane frame models.
