The main object of this experimental study is to investigate shear strength (and/or shear behavior) of SFRC (Steel Fiber Reinforced Concrete) beams using recycled aggregates. The main variables are longitudinal steel ratios(0.8 and 1.27%), shear span-to-depth ratios(a/d = 2, 3 and 4) and steel-fiber volume fraction(0, 0.5, 0.75 and 1%). A total of 24 specimens were tested under simply support and two-point loading conditions.
