Abstract

In the reinforced concrete structural elements, bond strength between steel reinforcement and concrete is as important as the compressive strength of concrete. Bonding between steel reinforcement and concrete is one of the important factors affecting the behavior of reinforced concrete elements, especially when experiencing cracks. Experimental and numerical studies with computer programs based on the finite element method (FEM) have been carried out by many previous researchers, however the studies that have been carried out are still using one type of diameter variation, while numerical modeling with variations in the diameter of reinforcement has never been carried out. In this numerical simulation with ABAQUS SE, the pull out test specimen from the results of previous research is a cylindrical concrete specimen with dimensions of 150 mm x 300 mm and diameter of reinforcement (d) 10 mm, 13 mm, 16 mm, 19 mm with development length (l = 10d) 100 mm, 130 mm, 160 mm, 190 mm, respectively. The specimen was modeled with 2 dimension (2D) one quarter circle (asymetric), the interaction of steel reinforcement and concrete was modeled as a cohesive behavior. The numerical simulation results show that the larger the diameter of the steel reinforcement used, the lower the bond strength value between the steel reinforcement and concrete, asymmetric and cohesive behavior models can be used to model the interaction of steel and concrete reinforcements, with good level of accuracy, where the difference in the value of bond strength, result of modeling and experiment are between 0.35% - 2.231%.
