Behavior of self-compacted reinforced concrete deep beams using steel plates as shear reinforcement Keywords: deep beam, self-compacting concrete, shear reinforcement, steel plate Introduction A reinforced concrete (RC) deep beam is one of the structural elements used in different structures, such as bridge bents, bridge girders, pile caps, and offshore structures. The shear deformation dominates the behavior of this element. Therefore, deep beams should be designed to have an acceptable level of shear strength by providing sufficient shear reinforcement. According to ACI 318-2014 (American Concrete Institute [ACI], 2014), the deep beam span should not exceed four times the overall depth. In addition, the shear span should be equal to or less than twice the beam depth. Different parameters play a significant role in controlling
