A random field approach is employed to characterize the inherent soil variability. This method is first compared to typical limit values from the literature to denote critical combinations of design parameters that can lead to exceedance of tolerable differential settlements. Then, reliability-based design equations are developed for the serviceability limit state (SLS) design of footings on cohesionless soils. The key parameters controlling the SLS are the allowable angular distortion, site variability, footing spacing. The results are given in a straightforward design format indicate that currently suggested deformation factors (resistance factors for SLS) equal to 1.0 are likely to be unconservative for most design situations. © 2009 ASCE.EnglishMooringReliabilitySettlement of structuresSoil structure interactionsSoilsUncertainty analysisAngular distortionsCohesionless soilDesign equationDesign parametersDesign situationsDifferential settlementsFootingsFoundation settlementKey parametersLimit valuesLoad capacityProbabilistic methodsRandom fieldsReliability based designResistance factorsServiceability limit stateSoil variabilitiesbearing capacitycohesionless soildesignestimation methodfootingprobabilityreliability analysissoil-structure interactionDesignArticle10.1061/(ASCE)GT.1943-5606.0000127
