3D FINITE ELEMENT MODELLING OF BOND-SLIP

2009-11-6  The behaviour of the concrete-steel interface must be described from stress-strain laws. Many constitutive relationships are presented in the literature. In this element, the contact surface between the steel bar and the concrete in the immediate vicinity of the steel bar is modeled by a bond stress-slip law which considers the special properties of the bond zone. The most important differences are that contact element has the dimension along the steel-concrete interface (it does not have physical dimension in other two directions) and it provides a continuous contact surface between - steel bar and concrete.
