Stochastic finite element method is main analysis method of complicated stochastic structure,and its mainly applies Monte Carlo simulation method which sampling method commonly is Latin Hypereube sampling method.But if level numbers for sampling are relatively high,sampling numbers will obviously is overmuch.In this paper,uniform sampling method is applied.Calculating examples which different factors and levels are selected are analyzed,and are compared with calculating examples that use Latin Hypereube sampling method.Calculating examples show as when sampling numbers by uniform sampling technique is obvious fewer with sampling numbers by Latin Hypereube,mean value and standard deviation of displacements,stress of node by two sampling methods are almost completely identical.Uniform samplings for stochastic finite element analysis have very well computing efficiency,and have certain applied perspective.
