unreinforced
Lacking added support
Unreinforced means lacking reinforcement—additional material or support that would add strength.
The term appears most often in construction: unreinforced concrete or unreinforced masonry contains no steel bars or mesh to improve tensile strength.
The unreinforced wall collapsed in the earthquake.
