Structure non-probabilistic reliability analysis

What is it about?

In this paper, a novel approach, i.e. convex model method of set theory is proposed to investigate the non-probabilistic reliability of metal structure.

Why is it important?

Considering the metal structure system of the bridge crane, finite element method is applied to obtain the stress response of the structure dangerous point. Then, the sample of stress response of the structure danger point and uncertain parameters are obtained. Finally, based on support vector machines (SVM), the structure implicit regression function of the system is replaced by explicit expression that calculates the non-probabilistic reliability of the structure. Results show that this approach is useful and efficient to solve the problem of non-probabilistic reliability in the metal structure.
