Abstract

The behavior of the pile subjected to lateral load depends on subsoil condition, sectional properties of pile, boundary condition of pile at top and bottom, and rigidity of the structure. Early attempts have been made to understand the response of the pile subjected to lateral loads using finite difference method (FDM) to obtain non-dimensional curve. Such curves are being used for determination of ultimate horizontal capacity as well as deflection, shear force, bending moment, soil reaction, etc., under design horizontal load. In the current study, an effort was made to determine the lateral load capacity using finite element method (FEM) for pile diameter, varying from 0.15 to 2.0 m in layered soil. The performance of the pile–soil system depends on the properties of soil and pile. The results obtained from the study indicated that the lateral capacity of pile foundation depends on cross-sectional area and material of pile, boundary conditions of the pile at top and bottom, and horizontal subgrade modulus of top soil (6D, where D is diameter of pile). For an increase in the diameter of pile (D–2D), lateral capacity of pile is increased by 2.5 times. © 2020, Springer Nature Singapore Pte Ltd.
