A Numerical Analysis on the Behavior of Single Battered Pile under Pullout Loading

Batter or raker piles are driven at an inclination with a vertical to resist large inclined lateral forces. Many structures like offshore and towers subjected overturning moments due wave pressure, wind load, ship impacts. Therefore in such structures, combination of the batter is used transfer compression tension forces foundation. This paper presents three-dimensional finite element analysis using PLAXIS 3D software study battered pile's behavior under effect pullout load. Several variables that influence pile capacity embedded sandy soil investigated. The models steel dense sand different angles (0, 10, 20, 30) degrees two embedment ratios, L/d (15 20). To clarify shape's on capacity, shapes used, circular diameter equal 20 mm square section 15.7×15.7 mm. These dimensions chosen achieve perimeter for both shapes. numerical results pointed increases increasing angle ratio, maximum values marked 20o. shape bending moment profile single curvature, peak located approximately midpoint pile, while zero value tip head.
