Abstract
For structures that only the predicted bounds of uncertainties are
available, this study proposes a Bayesian method to logically evaluate the nonprobabilistic reliability of structures based on multi-ellipsoid convex model
and performance test data. According to the given interval ranges of uncertainties, we determine the initial characteristic parameters of a multi-ellipsoid
convex set. Moreover, to update the plausibility of characteristic parameters,
a Bayesian network for the information fusion of prior uncertainty knowledge and subsequent performance test data is constructed. Then, an updated
multi-ellipsoid set with the maximum likelihood of the performance test data
can be achieved. The credible non-probabilistic reliability index is calculated
based on the Kriging-based surrogate model of the performance function.
Several numerical examples are presented to validate the proposed Bayesian
updating method.
