Abstract

Reliability of coastal structure is mainly based on maintaining the specified functions of the structure set during its design for a determined time interval and not reaching to the limit damage condition values due to the loading forces of structural resistance. A reliability based risk model is applied to the revetments located in the region between Piraziz-Sarp of the Black Sea coast highway by sampling the uncertainties of the random design parameters with probability distributions using physical properties of armor layer and significant wave height (Hs) of the study area. It is found that the factors affecting the reliability of the revetments are the armor layer slope (cotθ) and the relative stone density (Aδ). Damage probability of the structure in its economical life is also calculated.
