Title: Research of Reliability of Strength Degradation Structure Based on Interval Non-Probabilistic Theory
Abstract: According to the problem that the probability-based structural reliability theory is extremely dependent on statistical data of structural parameters and the problem of the structural safety margin equation is sensitive to the probability of structural parameters,the method for strength degradation structural reliability analysis is proposed based on non-probabilistic theory,and the corresponding mathematical model is established. The innovation is the combination of the latest research results of non-probabilistic theory and strength degradation structural reliability. So,it can be analyzed that the reliability of a strength degradation structure under static load and fatigue load with the distribution functions of the structural parameters unknown. By practical calculation example,it is proved that this method is more suitable to practical engineering comparing with traditional methods. This provides a new research approach to reliability analysis of the structure under static load and fatigue load simultaneously.
