Abstract
A dynamic centrifuge test and a static cyclic loading test were performed on a soil-footing model to investigate superstructure response and ultimate bearing capacity of a shallow foundation during strong shaking. A residual rotation angle of the shallow foundation after the dynamic test was 1/200 rad, even though the estimated ultimate bearing capacity during strong shaking was less than the self-weight of the footing and the measured overturning moment acting on the footing reached the ultimate overturning moment. The ultimate bearing capacity during strong shaking determines the ultimate overturning moment, but it does not affect the overturning of a shallow foundation structure when the safety factor of bearing capacity during static conditions is large.
