Reinforced concrete - Wikipedia
A balanced-reinforced beam is one in which both the compressive and tensile zones reach yielding at the same imposed load on the beam, and the concrete will crush and the tensile steel will yield at the same time. This design criterion is however as risky as over-reinforced concrete, because failure is sudden as the concrete crushes at the same,Reinforced Concrete Design,Reinforced concrete is a composite material, and the average density is considered to be 150 lb/ft3., determined from the amount of steel that would make the concrete start to crush at the exact same time that the steel would yield based on strain. ARCH 631 Note Set 10.1 F2013abn 7Reinforced Concrete Beam,The concrete on the top crushes before the steel yields (brittle) The steel yields before concrete crushes (ductile) The concrete will fail in compression at a concrete strain of ~0.003-0.004. The steel will yield at a steel strain of fy/Es or a steel stress of fy.

concrete | Definition, Composition, Uses, Types, & Facts,
Concrete that has been hardened onto imbedded metal (usually steel) is called reinforced concrete, or ferroconcrete.Its invention is usually attributed to Joseph Monier, a Parisian gardener who made garden pots and tubs of concrete reinforced with iron mesh; he received a patent in 1867.The reinforcing steel, which may take the form of rods, bars, or mesh,Concrete - Designing Buildings,Concrete strength. Concrete strength is determined by the force required to crush it and is measured in pounds per square inch or kilograms per square centimetre. Strength can be affected by many variables including moisture and temperature. The tensile strength of concrete can be improved with the addition of metal rods, wires, cables or mesh.Prestressed Wall Concrete Panels | Concrete Specialists,,Prestressed Wall Concrete Panels.
