**r7.01.21** Behavioral law (in 2D) for the steel-concrete bond: JOINT_BA
================================================================================

**Summary:**

The law of behavior JOINT_BA describes the phenomenon of degradation and rupture of the connection between steel bars and concrete, in reinforced concrete structures. This documentation presents theoretical writing in the thermodynamic framework and the numerical integration of the law, as well as the parameters that manage the model.

For its use, we will rely on finite elements of the joint type (see document [R3.06.09]) already existing in the code.
