Because the reinforced concrete elements work in conjunction with the material cracking behavior, the bonding process is very complex and depends on the shape of the reinforcement, mechanical characteristics of the materials and the intensity of loads. In general, the finite element method cannot emulate this complex process because the connection between elements at the node is fixed and slip behavior of reinforcement is not allowed. For this reason, the results obtained with the finite element method do not correctly describe the phenomenon. To address this, the study propose an improvement on the finite element method to eliminate the deficiency and describe the process with more accuracy.]]>Barnes, R.A. and G.C.
