reinforced concrete, concrete in which steel is embedded in this type of manner which the two products act jointly in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and often the compressive stresses inside a concrete structure. Simple concrete isn't going to quickly withstand tensile and shear stresses due to wind, earthquakes, vibrations, and various forces which is thus unsuitable in most structural applications.
