reinforced concrete, concrete in which steel is embedded in this type of manner the two supplies act jointly in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and occasionally the compressive stresses inside of a concrete composition. Basic concrete does not simply withstand tensile and shear stresses caused by wind, earthquakes, vibrations, and also other forces and is for that reason unsuitable for most structural applications.
