| Abstract: | A method of the reliability optimization design based on the modified genetic algorithm is given according to the features and difficulties of the reliability optimization design of structure with discrete variables.Using a 156 bar transmission tower and a simple ocean platform as examples,we testified the effectiveness of this method.Satisfuctory results are obtained not only in the optimization speed,but also in the quality of the solutions. |
| Keywords: | modified genetic algorithm discrete variable structure reliability optimization design |
