| Abstract: | For non-probabilistic reliability analysis of uncertainty structure with implicit limit state function,a method for non-probabilistic reliability analysis of uncertainty structure was presented on the basis of support vector regression,and analysis process of the method was given.Taking data samples and optimizing support vector regression parameters,the support vector machine after training was used to replace implicit limit state function.Using interval analysis method of non-probabilistic set theory and ... |
