Non-probabilistic structural reliability model based on ellipsoidal-bound model with restricted expansion
When insufficient data are available,probabilistic reliability method is invalid,but the non-probabilistic reliability method based on I-G (information-gap) model is a valid alternative.The most common I-G model,ellipsoidal-bound model,has been updated in this paper by acquiring information about span restrictions of uncertainty quantities and a corresponding non-probabilistic reliability index was proposed.The method for computing the reliability index was also given.The new model can reveal the influence of the span restriction of uncertainty quantities on structural reliability.
