???metadata.dc.description.abstract???: This paper describes the strategy of improving the strength and stiffness characteristics of timber and other wood based glulam structures. This is achieved by bonding Fibre Reinforced Polymer (FRP) composites to structural substrate externally. The need for strengthening structures - timber structures inclusive – is due to deterioration through extra service use, age and the need for sustainable development achieved by avoiding demolition and re-construction. Bonded FRP Composite materials have been proven to be an effective alternative to traditional steel plate strengthening techniques for concrete structures from results of a variety of researchers over the past two decades; this paper explores the use of this material for same strengthening purpose in timber structures. The experimental programme consisted in testing glulam flexural elements as follows: four different widths varying between 50, 100, 150 and 200mm, both in natural form and reinforced by CFRP. The tests were repeated thrice for each category for quality assurance. This made a total of twenty-four control and CFRP externally bonded specimen. All specimens were tested under four point bending at a loading increment rate of 0.5kN, the lateral deflection were recorded regularly. The data processing consisted of load, deflection and moment curvature plots construction which were then used for analysis and observations. The results revealed that there was a marked increase in the load bearing capacity of the timber flexural element, due to FRP strengthening and there was also an increased rigidity in the member characteristics.
