係留施設の信頼性設計における地震時上載荷重

抄録

In the design of port structures, it is important to decide the magnitude of actions rationally. When designing port structures by the reliability design method, it is necessary to evaluate probability distributions of actions. Recently, we observed the surcharge of bulk cargos on mooring facilities and estimated the design value of the surcharge based on the ISO2394. As a result, we took the design value of the surcharge during earthquake as zero. In this study, the design value during earthquake based on the ISO2394 was checked by using the first-order reliability analysis.
