3. Global models

3.1 Introduction

In the global approach, reinforced concrete is replaced by an equivalent homogeneous material. The parameters of this new material are determined by a numerical or analytical homogenization procedure.

There are currently 3 global models of increasing complexity in Code_Aster ( https://code-aster.org/spip.php?rubrique1 ) :

• GLRC_DM: Global Law Reinforced Concrete Damage model (takes into account loss of stiffness, tension/compression asymmetry, valid for moderate loads) (
