2004-08-26 · Twelve tests were conducted on reinforced concrete beams with three steel fiber-volume fractions (0, 0.5, and 0.75%), three shear span-depth ratios (2, 3, and 4), and two concrete compressive strengths (31 and 65 MPa). The results demonstrated that the nom-inal stress at shear cracking and the ultimate shear strength
Test results indicated that SFRC increases joint shear strength, as well as better ductility and better energy‐dissipation capacities. SFRC used in the joint core could reduce congestion in the steel reinforcement and ease construction difficulties. The joint with steel fibers had a better bond and improved the anchorage properties of the bar.
