- Using bonded fibre-reinforced polymer (FRP)laminates for strengthening wooden structural members hasbeen shown to be an effective and economical method. Inthis paper, properties of suitable FRP materials, adhesivesand two ways of strengthening beams exposed to bendingmoment are presented. Passive or slack reinforcement isone way of strengthening. The most effective way of such astrengthening was to place reinforcement laminates on bothtension and compression side of the beam. However, theFRP material is only partially utilised. The second way isto apply pre-stressing in FRP materials prior to bonding totension side of flexural members and this way was shownto provide the most effective utilisation of these materials.The state of the art of such a strengthening and variousmethods are discussed. Increasing the load-bearing capacity,introducing a pre-cambering effect and thus improvingserviceability which often governs the design and reducingthe amount of FRP reinforcement needed are some of themain advantages. A recent development on how to avoidthe requirement for anchoring the laminates at the end ofthe beams to avoid premature debonding is shown, and theadvantage of such a system is described.
