RELIABILITY BASED OPTIMAL DESIGN OF VERTICAL BREAKWATERS MODELLED AS A SERIES SYSTEM OF FAILURE

E. Christiani, H.F. Burcharth, J. Dalsgaard Sorensen

Abstract


Reliability based design of monolithic vertical breakwaters is considered. Probabilistic models of important failure modes such as sliding and rupture failure in the rubble mound and the subsoil are described. Characterisation of the relevant stochastic parameters are presented, and relevant design variables are identified and an optimal system reliability formulation is presented. An illustrative example is given.
