ANALYSIS FOR AXIAL LOAD DISTRIBUTION IN PILE IN A PILED RAFT FOUNDATION STIFF CLAY BY FINITE ELEMENT

In this paper piled raft foundation has been analysed by nonlinear finite element method. The three dimensional nonlinear finite element analyses predict the actual behaviour of axial load distribution. The axial load variation is nonlinear for all the piles. For all pressure the element stress is more than the element stress. For any pressure the nodal deflection is maximum at top and minimum at bottom. Up to certain height the element stress is almost zero for all pressures. After that height the element stress increases with increase in height. The element stress increases with increase in pressure the measurement of axial load distribution in pile in field is very difficult and costly.
