Eccentric loading, in which vertical or inclined wall surrounds one or more sides of the soil mass beneath the footing, is one of the recognized bearing capacity improvement techniques. The footing when provided with footing projection on one side such that it is an integral part of the footing it is called angle shape footing. Construction of footing projection at the base of the footing, confining the underlying soil, generates a soil resistance on projection side that helps the footing to resist sliding. In such a footing the soil particles near the footing projection are prevented from moving laterally thus footing projection to tilt in direction opposite the one in which the footing has tendency to tilt thus tilt of the footing can be reduced to zero by providing a downward inclined footing projection of required depth toward the loading side. The idea of angle as well as suitable length of projection has been used here by giving the footing an angle shape of variable projection angle. Various load inclination angles, load eccentricities, various angles as well as lengths of footing projection were investigated. Load displacement values for all cases were compared, and favourable design conditions were suggested. Laboratory work and numerical analysis were performed to study the behaviour of eccentric loading subjected to eccentric inclined load.
