Dynamic Properties of Nonreinforced Mass Concrete Beams
Tests were performed on four nonreinforced concrete beams to obtain low-frequency dynamic moduli for comparison with routinely obtained static moduli. Each concrete beam was 12 feet long by 16 inches square and had a 3-inch-diameter hole along the longitudinal axis. By applying cyclic loads 4.5 feet from the beam ends, the remaining 3 feet in the center was in a zero shear, constant moment condition. To prevent premature tensile failure of the beam, longitudinal compressive forces were applied by tensioning a steel rod inserted in the longitudinal axis hole. Total flexural loads were applied of from 5 to 25 kips and at frequencies from 2 to 10 hz. (Author Modified Abstract)
