Abstract—Today, buildings are exposed to the effects such as explosion and impact loads. Usually explosion and impact loads that act on the buildings such as nuclear power plants, airports, defense industry and military facilities, can occur occasionally on the normal buildings because of some reasons like drop weight impacts, natural gas system explosions and terrorist attacks. Therefore, it has gained importance that to research the effects of the impact loads in reinforced concrete buildings. Experimental studies realized for these structures and their structural members are very expensive and difficult. Therefore, development of computational mechanics has facilitated the modeling of such loading conditions. In this study, it was tried to numerically validate experimental results of the local damage of the reinforced concrete columns by the impacts of the high velocity projectiles. For the numerical studies, ABAQUS finite element software was used. The five standard series of reinforced concrete columns (100x100x280 mm) were numerically subjected to the projectile with a diameter of 9.54 mm to validate local damages. As a result of the analyses, depth profiles of the crater and appearance of the damages were obtained and compared with numerical results.
