Effectiveness of Angle Shaped Footings Resting on Soil under Eccentric Inclined Load

The paper presents a new type of foundation very much useful under the eccentric inclined loading conditions. The Angle Shaped Footing was introduced in 2000 and in this paper effectiveness by varying the angle as well as length of footing projection under the eccentric inclined load has been observed. Due to the inclination of footing projection the each pressure is increased which gives a little more resistance to the tilting. In the normal conventional footing due to eccentric loading the footing tilts and produces tension when the eccentricity exceeds 1/6 the footing width. After conducting a series of experiments and by verifying the experimental results by Ansys package which based on Finite Element Technique. It has been observed that the angle shaped footing becomes more effective when the angle of projection with vertical is in the range of 15° to 30°. The horizontal displacements in the footing due to inclined eccentric loading is also reduces to large extent and have been found to be maximum up to 1to 2% of width of foundation.
