Static and dynamic unconfined compression and tensile splitting tests were performed to correlate reinforced concrete beam behavior data gathered in other research. Nominal static compressive strengths ranged from 2,500 psi to 4,000 psi. An average constant rate of stress of 279 ksisec was applied to 18 dynamic compression specimens which showed an increase of 11 percent for dynamic ultimate compressive strength above static ultimate compressive strength. The increase in dynamic tensile splitting strength was determined empirically to increase at a greater rate than the dynamic compressive strength for the same concrete range of stress rates. Author
