This paper presents the results of cyclic-footing-load tests from the laboratory-model tests on square footings supported by a sand bed. The various intensity of cyclic load (loading, unloading and reloading) apply on the footing and then the elastic rebound of the footing corresponding to each intensity of loading obtains during the tests to determine the coefficient of elastic uniform compression of sand. The influence of sand relative densities of 45%, 63%, and 78% on behavior of footing under both static and cyclic loads case investigated. The results indicate that with increasing the relative density of soil the value of Cu increases. Finally the numerical analysis of footing under static and incremental cyclic loading is carried out by the FLAC3D program. The results show that the numerical results are in good agreement with experimental results.
