title = "Shear Strength of Steel Fiber-Reinforced Recycled Aggregates Concrete Deep Beams",
abstract = "– The effectiveness of steel fibers to improve the shear behavior of recycled aggregates concrete deep beams is investigated experimentally in this paper. Three large-scale concrete deep beams with a shear span-to-depth ratio (a/h) of 1.6 were tested. Two beams had a 100% recycled concrete aggregates (RCA) replacement ratio whereas one beam was made with natural aggregates (NA) to act as a benchmark. One of the RCA beams included steel fibers at a volume fraction of 1%. The use of a 100% RCA significantly impaired the beam stiffness, reduced the cracking load by 25%, and decreased the shear strength by 5%. The use of steel fibers in a RCA beam delayed initiation of shear cracks, improved the beam stiffness, and fully restored the original shear capacity.",
