In this study, the flexural strength and ductility of steel-timber composite beams were evaluated toenhance the structural performance of glued-laminated timber beams. Three specimens werefabricated, including one reference glulam beam and two composite beams. The composite beamswere constructed by attaching steel sections to the glulam beam using either liquid adhesive or screws. The experimental results showed that the structural performance of the steel-timber composite beamswas approximately 2-3 times higher than the reference glulam beam, indicating that both flexuralstrength and ductility were sufficiently ensured. Notably, the specimen constructed with liquidadhesive demonstrated superior structural performance compared to the screw-attached specimen. |
