Cross laminated timber (CLT) is relatively new and eco-friendly prefabricated wood product in a form of large structural panels used mostly for floors and walls. Cross-wise layer configuration enables both in- and out-of-plane resistance of CLT panels, providing significant structural flexibility. Modern structural demands, such as long-spans and heavy loads, make additional reinforcement necessary for CLT panels in bending. Improvements can be achieved by using advanced composite materials. This paper describes a design model developed to predict load-carrying capacity and bending stiffness of CLT panels reinforced with glass fibre reinforced polymer (GFRP) bars in tension zone. Model was calibrated for unreinforced CLT panels and modified to consider the effect of GFRP reinforcement with varying reinforcement percentage. Good agreement was observed between theoretical and experimental test results for reinforced CLT panels.
