Ground motions from large-scale blasting operations were used as excitation forces for vibration tests. A simple pile-supported structure was constructed in an excavated 3 m-deep pit. The test pit was backfilled with % water-saturated clean uniform by:

    The results of large scale model shell footings were compared with model tests in dimensionless manner. The improving in the ultimate load capacity of shell footing for both small and large footing was obtained and compared with flat footing. The load ratio for shell footing on reinforced sand were determined at different embedment depth (a/B).Cited by: Individual footings are one of the most simple and common types of foundations. These are used when the load of the building is carried by columns. Usually, each column will have its own footing. The footing is just a square or rectangular pad of concrete on which the column sits.
