Abstract
Due to the efficiencies and lightweight, wood I-beams have been extensively used for long-span applications in civil engineering. Buckling is the most likely mode of failure before material failure. This paper presents an analytical approach based on energy method to characterize flexural-torsional (lateral) buckling of cantilever composite wood I-beams with sinusoidal web geometry. The accuracy of this analytical model is verified through good correlations with existing Finite Element and testing results for I-beams with flat and sinusoidal webs.
