reinforced concrete, concrete during which steel is embedded in this type of way which the two materials act with each other in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and often the compressive stresses in a concrete structure. Plain concrete doesn't very easily withstand tensile and shear stresses due to wind, earthquakes, vibrations, and various forces and is consequently unsuitable in most structural applications.
