文摘

Uncertain static analysis with hybrid fields is investigated for the first time. New 2D interval field model is proposed for spatially dependent uncertainty. The extended unified interval stochastic sampling method is freshly proposed. Means and variances of the extreme bounds of structural response can be obtained. PDFs and CDFs of extreme structural response can be robustly estimated.
