Abstract
- Abstract: In Reinforced Concrete structures, the concrete damage configuration as well as the crack pattern distribution depend directly on bonding, and its implementation for numerical analysis is still complicated. In this work, a new thermodynamical non linear bond model is introduced taking into account tangential bond deterioration and coupling between tangential slip and normal decohesion/penetration. For FEM implementation, the model (based on a stress–strain relationship) is supported by a non-width interface element. The calibrated material parameters are grouped in four sets: elastic behavior; tangential degradation; crack friction and confinement; and normal behavior. Finally, some numerical examples are presented in this paper. [Copyright &y& Elsevier]
