| Abstract: |
| A method for structural reliability analysis based on generalized Lambda distribution was proposed.The first four moments for the performance function of structures were estimated by the sampled data firstly.Then the approximate generalized Lambda distribution for the probability density function of the performance function was determined by point estimation method and the failure probability of structures was evaluated by the definition of structural reliability directly.Numerical case studies showed that the generalized Lambda distribution has excellent ability to match several famous distributions.Finally,the accuracy and efficiency of the proposed method were verified by comparing with the Monte-Carlo simulation results of two engineering examples. |
