Lower grades of timber, such as that grown in Ireland, have high compressive strengths but low tensile strengths. Unidirectional fibre reinforced polymers (FRPs) on the other hand have high tensile strengths. Combining these two materials to form composite elements has many advantages including increased strength and ductility and a decrease in variability normally associated with timber elements. Additional enhancement of the structural performance can be achieved by prestressing the FRP prior to bonding with timber. This paper describes an analytical model which predicts the structural performance of these beams. Model predictions are validated using the results of laboratory testing of full-scale beams.
