Abstract
An analytical investigation examining the effects of wood properties on the flexural behaviour of glulam beams with fibre reinforced polymers (FRPs) was undertaken. A total of three different wood tension-to-compression strength ratios were investigated along with simple and U-shaped FRP configurations. A Visual Basic Application (VBA) module was developed to conduct moment–curvature analyses using published material models. Moment resistance increases of 1.95 and 1.19 were observed for members having tension-to-compression strength ratios of 0.5 and 2, respectively. The results also showed that the addition of FRP flexural reinforcement on members having a tension-to-compression strength ratio greater than one were the least effective, with the bending capacity being governed by the compressive strength in the wood. Moreover, the results also demonstrated that providing reinforcement beyond a certain limit did not contribute to a proportional strength increase.
