The response of reinforced concrete structural elements subjected to high intensity, short duration, dynamic loads is investigated. The analytical approach utilizes the Timoshenko Beam theory for the analysis of reinforced concrete beams and one-way slabs in the dynamic domain. Nonlinear material models, simplified approach for estimating strain rate effects and are used to derive the resistance of the element in flexure and shear. Sixteen cases that had been studied experimentally by other investigators, are analyzed and discussed.
