碩士 / 國立成功大學 / 系統及船舶機電工程學系碩博士班 / 93 / Basically, the failure problem of marine structures is affected by several factors, which are random in natural. If deterministic values alone are used as design parameters to describe those random factors while ignoring fuzzy characteristics in design, this may cause some economical or safe concerns for marine structures. In another word, the fuzziness lies in both strengths and loads. The purpose of this study is to employ the fuzzy set concept into the SORM. While utilizing an empirical SORM combined with the fuzzy theory to analyze a ship structure, a triangular membership function is applied to get intervals.
Two boats, a double-hull bulk carrier and an oil tanker are select as examples to analyze the fuzzy reliabilities based on both FORM and SORM. It is believed that this algorithm may provide more design information for ship structure designer.
