SUMMARY

The present paper focuses on selected plasticity and damage-plasticity models for describing the 3D material behavior of concrete. In particular, a plasticity model and a damage-plasticity model are reviewed and evaluated. Based on the results of the evaluation, enhancements are proposed, aiming at improving the correspondence between predicted and observed material behavior and aiming at implementing a robust and efficient stress update algorithm in a finite element program for performing large-scale 3D numerical simulations of concrete structures. The capabilities of the concrete models are demonstrated by 3D numerical simulations of benchmark tests with combined bending and torsional loading and combined compression and shear loading and by a large-scale 3D finite element analysis of a model test of a concrete arch dam.
