Özet

 The Reliability-based design and risk assessment model REBAD (1), which is used to predict the reliability levels of coastal structures that are subject to high damage risk and vast capital expenditures, was implemented to Wiseman’s Bridge revetment in UK by utilizing Van der Meer failure functions. The failure mode probabilities were calculated by the Second Order Reliability Method (SORM), where the failure surface was approximated by a quadratic polynomial having the identical curvature at design point. In this study, a methodology was suggested to determine the lifetime damage probability of coastal structures, which are subject to large tidal ranges and storm surges. As a result, REBAD was successfully implemented to a rubble mound revetment subject to large tidal ranges as a risk assessment study in order to point out the necessity for the development of deformation-based design (DD) methodology instead of the partial safety system used in EU countries.
