Abstract
The present disclosure relates to a device and a method for reinforcing a round section wood beam by the combination of a prestressed Fiber Reinforce Plastic (FRP) sheet and a high strength steel wire rope. The device includes an FRP sheet adhered to a bottom surface of a log beam in the length direction. A middle supporting piece is mounted in the middle of the log beam. An end part reinforcing anchoring piece is mounted at each of two ends of the log beam. FRP hoops are adhered to the log beam and are located between the middle supporting piece and each of the end part reinforcing anchoring pieces at intervals in the length direction. High strength steel wire ropes with both ends connected to the corresponding end part reinforcing anchoring pieces are respectively arranged on the two sides of the middle supporting piece.
