Abstract—Structures may be subjected to impact and blast loading because of various reasons. In recent years, the behavior of structural members under impulsive loading has been investigated both numerically and experimentally. Development in computational engineering has facilitated the modeling of extreme loading conditions. In this study, the behavior of reinforced concrete plates was modeled with ABAQUS commercial finite element software. In finite element model (FEM), Drucker-Prager (DP) material model and Classical Metal Plasticity (CMP) model were used for modeling concrete and reinforcing steel, respectively. The four reinforced concrete plates with fixed and free support were analyzed under impact load. The impact force-time, impact force-mid-span displacement curves and total dissipated energy were obtained numerically. The numerical results were compared with each other. Result showed that span size is effective parameter on impact behavior of reinforced concrete plates.
