Unreinforced
Unreinforced is an adjective used to describe materials, components, or structures that lack additional reinforcement designed to improve tensile strength or ductility. In civil and structural engineering, unreinforced elements rely on the inherent properties of the base material without added steel bars, fibers, or mesh.
Unreinforced concrete, for example, derives strength primarily from compression; its tensile strength is limited, and it
Advantages of unreinforced construction include simplicity, lower material and labor costs, and ease of construction. Limitations
Beyond concrete and masonry, the term unreinforced also applies to other materials that may be used without
