Modelling the mechanical behaviour of RC structures and, in particular, the steel-concrete interaction is one of the most difficult challenges of structural engineering. The lack of a robust and objective strategy for analysis of RC structures has discouraged the use of finite element method even for discontinuous regions of structures like beam-column joints where standard methods of analysis are no longer valid. The modelling strategy based on finite element method, presented in this work, is able to consider the confinement effect of the concrete on the bond behaviour of the reinforcement...
