Effectiveness of Random Field Approach in Serviceability Limit State Analysis of Strip Foundation

Abstract This work conducts a probabilistic inquiry on how the variability of parameter defining soil deformability affects settlement foundation located soil. The analysis addresses random model to relevantly estimate probability allowable deflection exceedance. constitutive is based either single variable or field. computations incorporate direct Monte Carlo sampling and variance reduction techniques, i.e. Stratified Sampling Latin Hypercube Sampling. focuses modelling by fields defined various correlation functions. One analytical means application non-homogeneous function capable reflecting strata. methods proposed in paper are tested standard example strip featuring load eccentricity. It proved that mode soil—a field—substantially results, settlements. was detected incorporating allows for valid reliability assessment respect Serviceability Limit State. adjusted functions allow realistic subsoil even case limited situ measurement database.
