Bayesian Credible Interval Finite Element Method Applied in the Bird-Striking Canopy Problem

摘要

For the uncertainty problem of structure strength of bird-striking canopy, firstly, the random finite element model is established by the prior random information. Secondly, according to the real test data, the Bayesian posterior distribution of the structure strength can be determined and the mean value and variance of the distribution without prior information also can be obtained, which can determine their bird-striking credible intervals of Bayesian theory. Finally, the example illustrates the effectiveness of the proposed method.
