- •
Structural stability assessment with random and interval variables is investigated.
- •
Proposed method calculates statistical characteristics of bounds of buckling loads.
- •
Correlated random variables can be considered and interval dependency is eliminated.
- •
PDFs and CDFs of bounds of structural buckling load are visualized.
- •
Statistical features of bounds are same as bounds of statistical features.
