BENDING BEHAVIOR OF TIMBER BEAMS STRENGTHENED USING CARBON FIBRE REINFORCED POLYMER
This research was conducted in order to investigate the bending behavior of timber beams strengthened with carbon fibre reinforced polymer (CFRP) plates. Five beams with the size of 100 × 200 × 3000 mm were tested. One of the beams was used as a control beam (unstrengthened) while the remaining four beams were strengthened before tested to failure under four point loading. The results showed that the strengthened beams performed better than the control beam with nominal increase in ultimate load and stiffness. The ultimate load was increased between 31.8% to 44.5% for the strengthened beams when compared to the control beam. The stiffness increased between 30.4% to 84.4% for the stengthened beams. CFRP plate bonding system has a good potential to be used in the new construction or rehabilitation process of timber structures.
