Seismic Bearing Capacity of Foundations on Cohesionless Slopes

Kumar, Jyant / Chakraborty, Debarghya

Abstract

By applying the lower bound theorem of limit analysis in conjunction with finite elements and nonlinear optimization, the bearing capacity factor $N_{γ}$ has been computed for a rough strip footing by incorporating pseudostatic horizontal seismic body forces. As compared with different existing approaches, the present analysis is more rigorous, because it does not require an assumption of either the failure mechanism or the variation of the ratio of the shear to the normal stress along the footing-soil interface. The magnitude of $N_{γ}$ decreases considerably with an increase in the horizontal seismic acceleration coefficient ( $k_{h}$ ). With an increase in $k_{h}$ , a continuous spread in the extent of the plastic zone toward the direction of the horizontal seismic body force is noted. The results obtained from this paper have been found to compare well with the solutions reported in the literature.
