Objectives
The present workpackage WP5 is entirely dedicated to numerical analysis, and it is aimed at investigating the behavior of buried steel pipelines under various loading conditions from ground-imposed permanent actions considering a wide range of geometric and material parameters for the soil and the steel pipe. More specifically, the objectives of WP5 are

• Simulation of experimental results conducted in WP4 (PGD) and calibration of numerical tools, developed in WP2
• Performance of an extensive parametric study on the PGD effects on pipelines, using the calibrated finite element tools

Evaluation of the numerical results for the purpose of determining the all possible failure modes of the buried steel pipeline under ground-induced deformations of permanent type
