Abstract
The reliability-based design method is regarded as the standard design method tobe applied in the next edition of technical standard for port and harbour facilities. In this study, we have focused on the design method for fenders for berthing ship. First-Order Reliability Method is applied in order to calculate the failure probability of fenders by using the probability distributions of design parameters. Safety levels of fenders with present design method are clarified quantitatively. Moreover, partial safety factors for level-1 reliability-based design method are proposed.
