A beam-bar finite element formulation of a laterally loaded pile problem is developed. The approach taken utilizes the beam on elastic foundation coefficient of subgrade reaction method. The three loading conditions of a lateral load or applied moment on a free-end pile and a lateral load applied to a fixed-end pile are analyzed for a range of soil strength variations with depth. Curves are developed which present the maximum values as a function of the soil-structure stiffness ratio. A design procedure with an example is given to show the use of these curves in the design of any laterally loaded pile system.
