【Abstract】 A fuzzy comprehensive judgment method is used for assessment on risk of cracks of offshore steel structure. The assessing procedures include classifying risk of cracks, certain factors collection, certain weightiness collection, single factor judgment and comprehensive judgment of risk, and calculating equations for each proceduce are presented. 3 different methods, deterministic method, reliability and risk assessment, can be used to judge safety margin of the offshore structure, and the related calculating equations are presented.更多还原
