| Abstract: | A nonlinear fatigue damage model is investigated. Both genetic algorithms and ev0lutionary programming are applied to the fatigue reliability-based optimum design of a simple off shore platform. The reliability of the fatigue damage model and the effectiveness of genetic algorithms and evolutionary programming which are used are shown by the results of optimum design. Some characteristics of genetic algorithms and evolutionary programming are discussed. |

| Keywords: | Genetic algorithms evolutionary programming fatigue reliability-based optimum design damage mechanics |
