摘要: An alternative approach of analyzing laterally loaded piles in the ubiquitous spreadsheet platform is presented. The numerical procedure couples nonlinear pile flexural rigidity ( Ep Ip ) with p-y analysis. deterministic study then extended to carry out reliability analysis, which reflects uncertainties and correlation structure underlying parameters. index evaluated based on intuitive perspective an expanding equivalent ellipsoid original space random variables. This paper investigates two modes failure: deflection bending moment, considers non-normal Spatial variability soil medium accounted for by incorporating autocorrelation model. spreadsheet-based can also be coupled stand-alone programs via response surface method. probabilities failure inferred from indices agree well Monte Carlo simulations. Simple reliability-based de...
