| Abstract: |
| In order to overcome the shortcomings of the traditional methods of the reliability index calculation in model description and calculation,the improved shuffled frog leaping algorithm was introduced.The adjust strategy of pheromone of ant colony algorithm was employed to solve the local optimum problem of the basic shuffled frog leaping algorithm.The improvement can expand the search scope of the algorithm and help the algorithm jump out of the local optimal results.Then,the improved algorithm was applied to the calculation of the structural reliability index.Engineering practice shows the effectiveness of the improved algorithm. |
