Abstract:
The results of loading tests on normal, medium, and high-strength concrete cylinders under axial compression are discussed. Special attention is paid to the descending part of the stress-strain curve, which is known to be very steep for high-strength concrete. Addition of steel fibers has a beneficial effect on the strain-softening behavior and significantly increases the toughness, as measured by the area under the stress-strain curve.
