Abstract
Pile foundations of offshore structrues are subjected to significant lateral loads. The effect of load eccentricity has been demonstrated by conducting tests on model piles. A method has been proposed to estimate the load-deflection behaviour of piles at different eccentricities. For cyclic load application the deflections and moments in the piles are observed to stabilize after some cycles depending on the load level. Correleations have been proposed to predict the depth at which maximum moment occurs and the depth below which moments are negligible. The post cyclic behaviour of piles has been explained in terms of the changes in the soil strength behaviour.
