This study investigates the structural performance, physical–mechanical properties, and fabrication technology of I-shaped timber beams composed of solid wood flanges and an OSB (Oriented Strand Board) web. The proposed composite beam system is aimed at improving load-bearing capacity, bending stiffness, and serviceability performance while maintaining environmental sustainability and economic efficiency. The interaction between timber flanges and the OSB web is analyzed using analytical expressions for bending, shear, and deflection. Composite action is ensured through the combined use of PVA-based adhesive bonding and bolted mechanical connections. The analytical model confirms that the I-shaped timber beam provides high structural efficiency and is suitable for application in lightweight and medium-span building structures.
