The paper presents the results of the study on a model of a glued wooden beam with composite reinforcement. The authors use a software package using the finite element method COMSOL Multiphysics to model and study the stress-strain state of spatial multilayer wooden structures with reinforcement. The main focus is on analyzing the stress and strain characteristics of the beam under various loads. The paper considers the advantages of composite reinforcement efficiency and its influence on increasing the strength and durability of wooden structures. The authors pay special attention to the integration of experimentally obtained characteristics of wood and composite materials into the numerical model. It increases the accuracy of the modelling results. When constructing the 3D model, we have used a simplified wooden model as a transversal-isotropic body. It allows taking into account uncertainties on orientation to the tangential and radial directions in the beam. The results obtained confirm the increased load carrying capacity and reduced deformations in the beam due to the use of composite reinforcement compared to traditional wooden structures. The use of a 3D model of a glued beam with composite reinforcement also provides reduced research costs compared to in-situ experiments.
