STUDY ON PROBABILITY DISTRIBUTION OF REACTION FORCE OF FENDERS

Abstract

It is necessary to evaluate the probability distribution of variables in order to apply the reliability-based design method. In this study, probability distribution of reaction force of fenders acting on quay walls is studied. For the purpose, we firstly evaluated the probability distribution of berthing energy acting on fenders. We then evaluated the probability distribution of reaction force by using performance curves of fenders. It was found that probability distribution of berthing force is complicated and not easy to handle for probabilistic design methods. Therefore we conducted first-order reliability analyses and proposed the probability distribution that is suitable to reliability-based design method.
