Studies focused on the effects of supporting conditions on the behavior of reinforced concrete slabs subjected to static and dynamic loadings may be found in the literature. However, in the literature no study was found about the effect of variation of the support conditions on the behavior of slabs subjected to impact loads. Consequently, an experimental study was performed on the behavior of reinforced concrete slabs subjected to impact loading. Eight (8) square reinforced concrete slabs with dimensions 500 x 500 x 50 mm were tested by changing two parameters; (i) support type, (ii) support layout. In scope of the experimental study, 4 different support layouts were considered on 2 main support types (i.e. fixed and hinge supports). In the experimental study, impact loadings were applied to the specimens using a drop weight impact test set up. Acceleration-time responses of those specimens were measured by dropping a standard-weighing hammer from a height of 500 mm. Effects of the parameters on the damage distribution, number of drops, acceleration-time, velocity-time and displacement-time responses were investigated. Variations of velocities and displacements were calculated for all specimens by using measured accelerations. Finite element analyses conducted using ANSYS Explicit STR software was used to simulate the experiments. It was observed that the results obtained using the numerical model was in good agreement with those obtained from the experimental study. (C) 2015 Elsevier Ltd. All rights reserved.
