| Abstract: | Reliability analysis for ultimate strength of ship hull girder requires consideration of the following four aspects:(1) failure function; (2) ultimate strength; (3) loads; (4) method of reliability analysis. A modified Monte Carlo method combined with variance reduction techniques(VRT) of conditional expectation(CE) and antithetic variates(AV) was adopted to calculate the failure probability of ship hull girder. An example was analysed to verify the efficiency and rationality of the proposed method. |
