Research on the structure non-probabilistic reliability model based on rough set theory

Zhao Jia

There are all kinds of uncertain variables in the engineering structure analysis. The uncertain parameters of structures are expressed by rough variables easily. According to the non-probabilistic structural reliability analysis method, rough k-means, optimal model and interval analysis, a new methodology for structural reliability computation is presented. It fully considers the influence of uncertain variables. Examples of practical application are given.
