Seismic Interference Effect of Two Nearby Square Footings
In the present study, an attempt has been made to model the seismic response of two perfectly rough embedded square footings placed in close spacing on layered soil deposit resting on strong bed rock by using the explicit finite difference code FLAC3D. The footings carry equal static load without violating the ultimate bearing capacity under static condition. The soil is assumed to follow Mohr-Coulomb failure criteria with non-linear failure envelope. The results are presented in terms of horizontal x-acceleration response on the top of the footing, and the settlement of footings under seismic condition with the variation in clear spacing between two footings. The present theoretical investigation indicates that the settlement of closely spaced footings under seismic condition is found to be higher than that of single isolated footing.
