Lpile 2018 Technical Manual -

At the heart of the Lpile 2018 analysis is the solution of the fourth-order differential equation for a beam-column. The software uses the finite difference method to discretize the pile into segments, allowing for the calculation of deflection, rotation, bending moment, and shear force along the pile length. The manual details how the software accounts for pile stick-up, varied boundary conditions at the pile head, and the effects of axial load on lateral stiffness (the P-Delta effect). Understanding p-y Curves

The "p-y" method is the industry standard for lateral pile analysis, where "p" represents the soil resistance per unit length and "y" represents the local lateral deflection. The Lpile 2018 Technical Manual categorizes various soil models based on extensive field testing: Designed for saturated soft clays. Lpile 2018 Technical Manual
