Method for strengthening concrete or timber structures using CFRP strips and concrete or timber structures strengthened by this method
This method is suitable for the strengthening of concrete or timber structures by applying prestressed Carbon FRP or Glass FRP lamella. At least one groove is cut into the concrete or timber structure along the direction in which the concrete or timber structure is to be strengthened. The grooves are filled with epoxy resin and a layer of epoxy resin is put onto the entire section to be equipped with the CRFP or GFRP lamella. The lamella is prestressed and anchored at both ends. U-shaped brackets are then being put over the two end sections of the CFRP or GFRP lamella by inserting and submerging its both U-legs into holes filled with resin as well. These holding brackets are then tightly pressed onto the CFRP or GFRP lamella to prevent cracking or fracture of the concrete or timber and bending away of the extremities of the CFRP or GFRP lamella.
