Seismic Bearing Capacity of Strip Footing Subjected to Eccentric Load

Abstract

Reinforced soil bed is improved soil strata from its weak unreinforced original form. By introducing reinforcing ties or strips the soil bed improves on its strength and is rendered less settleable. The compensations of introducing reinforcements have been widely studied by many researchers. The present work has evaluations, formulations and calculations for bearing capacity under certain seismic excitation when the strip footing on reinforced soil was subjected to eccentric loading. The contrast of bearing capacity of the footing when it is subjected to eccentric loading with that when subjected to uniform seismic loading and uniform vertical static loading has been done. The benefit of using layers of reinforcing ties in refining the seismic bearing capacity of the footing has been established.
