ABSTRACT: Batter piles are very effective in resisting lateral and torsional forces acting on the structure. Experimental work was carried out in the laboratories on 2 x 2 batter pile groups to investigate the torsional and lateral response of batter pile groups in sand. Lateral and torsional load tests were conducted on pile groups with three different orientations such as vertical pile group, one side battered pile group and two side battered pile group with different batter angle 00, 100, 200, 300 and 400. It was found that the lateral capacity of batter pile groups increased with increasing the batter angle up to 30 degree. It was also found that torsional capacity of batter pile groups increased with increasing the batter angle up to 30 degree. One side battered pile group shows slightly greater lateral capacity than two side battered pile group, but at the same time, two side battered pile group shows greater torsional capacity than one side battered pile group.
