A response surface method for reliability analysis based on iteratively-reweighted-least-square extreme learning machines (IRLS-ELM) is explored in this paper, which, highly nonlinear implicit performance functions of structures are approximated by the IRLS-ELM. Monte Carlo simulation then carried out approximate IRLS-ELM structural analysis. Some numerical examples given to illustrate proposed...

In seepage problems, the coefficients of permeability in Laplace equation are usually assumed to be constant vs. both space and time; but in reality these coefficients are variable. In this study, the effect of material deformation due to external loads (consolidation) and variation of head in the consolidation process are considered. For the first case, formulation of kx and ky can be defined ...
