ABSTRACT

Wood has excellent performance as a renewable material, which can improve the long-term carbon fixation capacity and increase the economic added value when used in the construction field. A new type of cold-formed thin-wall steel-glulam composite beam is proposed in this paper. Six composite beam models are established by ABAQUS to analyze the failure pattern and mechanism. The influences of steel strength, the thickness of steel, and the thickness of glulam at flanges on the flexural performance of composite beams are analyzed. The results show that the glulam at the lower flange is damaged before the glulam at the upper flange, which leads to the bending failure of the composite beam. Increasing the above parameters can improve the flexural performance of the cold-formed thin-walled steel-glulam composite beam, and the thickness of the glulam at the flange has the greatest influence.
