Contradictory behavior of vertical pile subjected to inclined load was found in literature, so the current research was devoted to investigates the behavior of single vertical steel hollow pipe pile embedded in sand subjected to compressive inclined eccentric load through MIDAS GTS/NX 2019 FEM package. 3D numerical analysis simulating the pile-soil system have been carried out. The effects of the loading inclination angle and the pile length and diameter on the performance of the pile were investigated. Inclined load carrying capacity and pile stiffness as well as lateral deformation profiles along the pile were presented. The pile head displacement and pile stiffness are significantly affected by loading inclination angle. It was observed that, P-Y curves of the pile-soil system are independent of loading inclination angle α. also the pile length and diameter are markedly affecting the behavior of the pile.
