Sensitivity analysis of the effects of liquefiable soil deposits on differential settlement of buildings by numerical modelling
Differential settlement is one of the key causes of damage to buildings on liquefiable soil deposits. Although important technical developments in geotechnical earthquake engineering have provided significant insights into the performance of buildings on liquefiable soil, the current solutions for the mitigation of the associated damages are based on expensive mat foundations. While buildings with isolated footings are unexpensive, they are more susceptible to differential settlements. Differential settlement can not only make a building unusable and irreparable, but also introduce large stresses into a building that can result in damage and collapse of the superstructure. The main objective of this work is to investigate the key parameters that influence building differential settlements and tilting through nonlinear effective stress fully-coupled dynamic numerical simulations in PLAXIS-2D®. In this paper, 1-bay and 2-bays buildings on a mat foundation will be compared with an equivalent building on isolated footings.
