Rebar Yield Strength: Grade, Ductility, and Beam Failure
Rebar yield strength is the stress at which reinforcing steel begins substantial permanent deformation. In a well-detailed reinforced-concrete flexural member, designers generally seek ductile, tension-controlled behavior: the tension reinforcement yields and gives visible deformation before the concrete compression zone crushes. Yielding is not the same as fracture, and specifying more or stronger rebar does not … Read more
