Abstract: This paper presents a design of a new reliability calculation method based on uniform test,which organically combines artificial intelligence network.Artificial neural networks abandons the finite element method (FEM) and applies this method,because  the new law can greatly reduce the amount of computation.First,according to the distribution of the random variable,limited samples are extracted by uniform test,which are taken as for the input parameters finite element analysis.Secondly,based on the finite element analysis results,the limited training samples are used to  construct the optimal artificial neural network.Optimal artificial neural network generalization ability is applied to obtain a valid response,and then the reliability index of the structural system is calculated.Finally,this calculation method provides a new attempt  for reliability analysis in the actual testing of complex systems,which is proved to be  practical and effective.
