Mixed Loading in Piles - Reaction Module Method

This lecture covers the analysis of piles subjected to mixed axial, horizontal, and moment loads, introducing the reaction module method to model the soil as springs, despite its limitations in capturing soil deformation. The method involves writing a behavior law for the springs, solving the resulting equation with boundary conditions, and considering the non-linearity of the reaction. It emphasizes the importance of correctly modeling soil-structure interaction using finite elements for accurate results, especially in cases where interactions significantly affect the pile behavior.
