Analysis of angle shaped footing under eccentric loading

Footings are often subjected to eccentric loading due to (1) moments with o r without axial forces; (2) the oblique loading; and (3) their location nea r the property line. Due to eccentric loading, the footing tilts and the pr essure below the footing does not remain uniform. The tilt of footing incre ases with an increase in the eccentricity and the bearing capacity reduces considerably. Therefore, footing sizes increase and make the design unecono mical. The finite-element analysis of an angle shaped footing under eccentr ic loading has been carried out in the present study. One side vertical pro jection of footing confines the soil and prevents its lateral movement. It was concluded that footing subjected to uniaxial eccentric loads can be des igned for no or negligible tilt by giving the footing an angle shape. The d epth of footing projection will depend upon the eccentricity width ratio.
