DOI: 10.1016/j.cma.2018.03.013
Abstract: Abstract In both mathematical theory and engineering application, the uncertainty propagation problem with incomplete knowledge, especially when different types of epistemic uncertainties exist simultaneously, has been recognized as a challenge issue. By using interval variables… read more here.

DOI: 10.1016/j.cma.2019.112718
Abstract: Abstract The interval identification of dynamic loads for uncertain structures was performed primarily by the interval perturbation method (IPM). Influences of structural epistemic uncertainties on unknown loads cannot be effectively quantified for now and the… read more here.

DOI: 10.1016/j.probengmech.2019.103001
Abstract: Abstract The small first passage probability of nonlinear dynamic structures under nonstationary seismic excitation implies a prohibitive computational demand because of the epistemic uncertainties rooted in structure system. In this work, a hybrid Kriging-high dimensional… read more here.

DOI: 10.1177/87552930231157424
Abstract: The need for US Geological Survey (USGS) National Seismic Hazard Models (NSHMs) to report estimates of epistemic uncertainties in the hazard (e.g. fractile hazard curves) in all forthcoming releases is increasing. With fractile hazard curves… read more here.
