"In fact, piles foundations are usually used to support offshore and inshore huge structures that often subjected to cyclic load from any load condition and sometimes produce a torque caused by eccentric transitions of load. Therefore, to find out how pile group would behave under eccentric one-way cyclic loading with static axial load, a model test of 2×2 was carried out in sandy soil. The pile group consisted of aluminum piles and were set up in a sandy soil with a three-pile spacing of (i.e., 3D, 5D and 7D). The cyclic load is applied with three eccentric distances, at center of piles group, at 0.25S, and 0.5S. It can be concluded that, when the distance of eccentricity increases the lateral displacement increase and reached to 54%. The results also show that the increase in piles group spacing can reduce the lateral displacement up to 26%. As well as, the twist angle increases and reach to about 17ᵒ with increasing the eccentricity and reduce pile cap spacing."
