Prestressed concrete beams concreted in two stages, having their interface at the level of the centroidal axis, are called prestressed split beams. Only the bottom portion of this split beam is prestressed. This report deals with an experimental study of the dynamic behavior and resistance of this type of prestressed beam. Nine simply supported prestressed split beams were tested under dynamic loading and three beams were tested under static loading. The variables studied in this investigation were the interface roughness and the reinforcement parameter rfy r and fy are the percent and yield point of the web reinforcement across the interface.
