  ABSTRACT        The present paper studiesthree bond-slip models (CEB-FIP, Harajli and Farra) based on thefindings of previous experimental studies in order to investigate the influence of bond-slip on crack spacing and crack propagation in RC panel. For this purpose, the RC panel is modeled using a lattice type numerical model in ABAQUS software, in which the cracking process is represented by the damage of the concrete bar elements. The lattice models are proposed based on an improved cracking criterion, which is derived from fracture mechanics principles. Concrete and steel are combined based on a model of the interaction (bond-link) through bond-slip in order to describe the behavior of the composite reinforced concrete material. The results of this analysis showed that the effects of diverse bond-slip models on crack spacing, crack propagation and damage localization are significant. Manuscript profile
