STUDY OF NON-PROBABILISTIC RELIABILITY MEASURES OF STRUCTURES BASED ON INTERVAL

Jing Ma

Abstract

In the case of scarce data or insufficient information available,a non-probabilistic set model is valid alternative to structural reliability analysis.The non-probabilistic reliability measures based on interval and their interrelations are investigated.Three kinds of non-probabilistic reliability measures based on interval,which are reliability index,set based reliability measure and safety possibility degree are compared.The non-probability set-based reliability nature and the computational method have been studied.In the stress-strength interference case,the non-probability set-based of reliability analytic method is suggested to be applied to carry on the structural reliability analysis,then several common non-probability set-based of reliability computational method for stress-strength combination are also proposed.At last,the conclusion is verified by an example.
