Pile used as the foundation in many cases may be subjected to inclined compressive loading condition. In such cases, overall behaviors of the piles are estimated from available conventional theoretical approaches. As there are limited experimental studies available on behavior of vertical piles subjected to inclined compressive loads, in this paper, an attempt has been made to study the behavior of single pile subjected to varying inclined load until failure with angle of applied load varying from 00 to 900 from vertical axis of pile through a rigorous experimental program. Increment of load inclination is kept small so as to facilitate a precise and detailed study of effect of load inclination on inclined load carrying capacity of a vertical pile. Axial, lateral and inclined load carrying capacity for pile of various slenderness ratios are predicted from available theories and compared with present study. Influence of vertical and
lateral components of the loads on horizontal and vertical displacement of the pile head is discussed. Variation of ultimate load carrying capacity of vertical pile with angle of load inclination is also reported through polar diagrams.
