Simplified Evaluation of Liquefaction-Induced Building Settlements
Liquefaction-induced settlement of buildings on shallow foundations requires evaluation of shear-induced, volumetric-induced, and ejecta-induced ground settlement mechanisms. There are few procedures for estimating the shear-induced component of building settlement due to liquefaction. Nonlinear dynamic soil-structure interaction (SSI) effective stress analyses can capture this mechanism. A simplified procedure was developed that provides building settlement estimates consistent with those calculated from the dynamic SSI effective stress analyses of a variety of buildings for generalized subsurface conditions. The liquefaction-induced building settlement (LBS) index is employed to characterize more complicated ground conditions. The proposed simplified procedure is applied to several field case histories and shown to provide estimates of liquefaction-induced building settlement consistent with those observed. Recommendations for evaluating building performance at liquefiable sites are shared.
