  • Method of externally strengthening concrete columns with flexible strap of reinforcing material
    Patent number: 6219991
    Abstract: A method of repairing and strengthening a concrete column includes wrapping a flexible strap of reinforcing material circumferentially around the exterior of a concrete column and longitudinally along at least a portion of the height of the concrete column, and then fastening the flexible strap of reinforcing material to itself to secure it to the concrete column such that external lateral reinforcement of the concrete column is thereby provided which increases the strength, stiffness and ductility of the concrete column. The repairing and strengthening method also includes applying a tension force to the flexible strap of reinforcing material before, while, or after it is wrapped around the exterior of the concrete column. The flexible strap of reinforcing material has a predetermined length, width and thickness.
