Abstract: An embedded slip model is presented for finite element analysis of reinforced concrete structures. The bond element simulating the interface of reinforcing bars and concrete is embedded into the concrete element. To obtain the relative slip, the top and bottom faces of the bond element are constrained to have compatible deformation with the concrete and the reinforcement element respectively. Using the virtual work principle, the equilibrium equation is obtained by assembling the stiffness of each component, i.e. concrete, reinforcement and bond element. Analyzing a testing reinforced concrete beam by the embedded slip model, the loading-capacity, crack distribution and failure mode are consistent with the experimental results. The numerical simulation shows that the embedded slip model can be applied to analyzing reinforced concrete structures.
