| Abstract: | The reliability of probabilistic structure has been analyzed based on a perturbation stochastic element-free Galerkin method(PSEFGM).PSEFGM has characters of high precise and element-free.Numerical example shows that stochastic element-free Galerkin method has excellent characters and applied prospect in reliability analysis of probabilistic structure. |
| Keywords: | Stochastic element-free Galerkin method Random field Structural reliability |
