Pile-Soil Interaction

Coupled Fatigue Analysis in Time Domain

The wind turbine and foundation are subject to fatigue damage from environmental loading (wind, waves) as well as turbine loading. For the fatigue analysis, the wind turbine design code recommends time domain simulations with completely coupled turbine dynamics under simultaneous wind and wave loading.


Linear Dynamic Analysis

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.
