REINFORCEMENT HANDBOOK - Structural Engineers

Aug 02, 2012  Reinforcement includes deformed bars, plain bars, wire, fabric and steel products, all of which increase the tensile and compressive stress carrying properties of concrete. Steel reinforcement is also the essential contributor towards crack control of concrete structures. Reinforcing Bar A bar is a finished product rolled to close tolerances.
