摘要：
A new way to obtain the probability density function (PDF) of response was presented. The sample of structure response was obtained using Neumann SFEM. Then, the PDF of response was fit by means of the linear combination of Hermite orthogonal polynomial. At last, the hypothesis test was used to verify if the fit PDF can represent the actual probability distribution of the random variable. Results show that the proposed approach is practically efficient and can be applied to engineering practice.
