Abstract:The energy absorption and strength carrying capacity of plain concrete subjected to both static and dynamic loading were investigated using sixty 6 x 12 in. cylinders. Three concretes with nominal strengths of 2500, 3700, and 5000 psi were tested with rates of stress ranging from 7.1 to 17 x 106 psi per sec. The lower and intermediate rates of loading were obtained through the use of the conventional hydraulic testing machine. In each test the specimen was supported in a load frame which had a floating head to insure proper load distribution. The compressive strength and energy absorbed increased with the increase in the rate of loading, with evidence of becoming a constant value at the higher rates of loading. There were also increases in the secant modulus of elasticity and the strain as the rate of loading increased. The internal strain, both static and dynamic, was larger than the external surface strain and also there was evidence that the concrete specimen behaved visco-elastically under dynamic loading.
