This research was carried out in order to evaluate the bond characteristic between concrete and deformed bar in Macro level by meso-scale analysis using Rigid Body-Spring Model (RBSM). In the analysis, lugs of deformed bar were modeled considering the geometry. By the meso-scale analysis using the stress-strain relationship obtained from the tests in macro-scale, it was possible to understand the development of the internal cracks around the lugs as well as the development of the cracks and the bond behavior in macro-scale. Moreover, it was investigated the effect on the bond behavior of the lug spacing and the stiffness of the bar. As the results, the lug spacing was influence factor and the stiffness of the bar did not influence to the bond behavior.
