Behavior of Strip Footing/s above Void in Sandy Soil

This paper presents a numerical study that utilizes finite element analysis under the plain strain condition performed on sand with isolated strip footing and two closely spaced footings above continuous void. The Bearing Capacity Ratio (BCR) efficiency factor ζγ were introduced to determine effect of void ultimate bearing capacity footing/s. influence various parameters including spacing (S/B) (i.e. edge edge) between interfering along location shape studied. In general, results indicate presence reduces affects performance footing/s there is critical value S/B beyond which becomes negligible.
