| Description | Introduction The bond between concrete and reinforcement is the basis for steel reinforcement and concrete to act together as a composite. In particular cases such as gravity-designed structures subjected to lateral loads, strength and deformation of the structure may be determined by bond-slip behaviour between the reinforcing bars and the concrete. Bond zone element (contact element) [1] has been proposed to include the bond-slip effect in the finite element analysis of RC structures. In the bond zone element, the contact surface between reinforcing bars and concrete are modeled by using a constitutive law, which represents the properties of the bond zone (Figure 1). Some researchers solved the truss element with bond-slip, and other researchers solved frame element. The complexity in the modelling of each individual reinforcing bars causes these models to be unpopular in the analysis of reinforced concrete structures. In this study, a panel element will be used to include bondslip effect between concrete and smeared reinforcement (Figure 2). This element simplifies the modelling of the reinforcing bars, since they will not be modelled individually but will be smeared in the reinforcement panel.
