Load carrying behaviour of thrust rings for transferring longitudinal pipe forces

This paper gives an overview of the project, showing the test setup and the main results. To get realistic FEM-results, the material model for concrete (CDP - Concrete Damaged Plasticity model in ABAQUS) has to be modified. A short overview of the improved parameters is given. Finally the new insights in the load carrying behaviour of thrust rings are shown and the basics for a design model in practice are presented.
