Sensitivity Analysis of Random and Interval Uncertain Variables Based on Polynomial Chaos Expansion Method
The problem of characterizing the sensitivity indices of structural performance considering random and interval uncertainty variables simultaneously is analyzed. Data-driven polynomial chaos expansion (PCE) is established to treat random variables with arbitrary input uncertainty information, and su...
