In this paper the current state of a research project on the behavior of reinforced concrete slabs subjected to impact loads are presented. As one part of the project several slabs were tested under varying conditions. As a result there failure behavior is analyzed and parameter dependences are studied. Variations like the drop height and drop mass and there substituted drop velocity and energy, the influence of the concrete strength and the level of reinforcement are part of the full project. Additional parameters like impactor size and shapes are evaluated in peripheral. Due to the large number of slabs and parameters combination a consistent database will be created for later benchmark tests and calibration of prediction models. The presented paper gives some insight in the methodology, the problems which need to be solved and first principal example results for public discussion.
