Influence of Steel Fibers on Cracking Behavior of Ordinary Reinforced Concrete Structures

摘要

The cracking behaviour of concrete beams having longitudinal tension reinforcement and various combinations of volume and aspect ratio of hooked end steel fibers was investigated experimentally. Eight full-scale beams have been tested. The section diemsions (200 x 350 mm~2), span length (3250 mm), concrete compressive strength and longitudinal tension reinforcement were kept constant for all beams. The beams were tested at a cube compressive strength of about 40 MPa.
