Pile Soil Interaction Analysis (PSI) with nonlinear soil spring
The computer simulation of a pile foundation takes into account the pile stiffness and the lateral behavior of the soil.
The nonlinear behavior for pile soil interaction is considered based on the geotechnical data of P-Y, T-Z, and Q-Z curves for the analysis to obtain a rigorous solution of the pile-soil-structure interaction.
Iterative analysis is carried out by the PSI program until reaching the pile head displacement convergence. Thereafter, PSI extracts the final pile head loads and analyzes the pile.
