Abstract

An OSB webbed bamboo I-shaped beam was presented. Tests were performed on 10 composite beams to investigate the effects of shear span ratio and stiffeners on the failure mode, strength and ductility using the four-point bending load. Experiment results showed that the web and flanges of beams possessed good load-carrying capacity and the initial damage of the wood-bamboo composite beams was lateral buckling, and the main failure mode was the delamination of OSB and shear failure of the web. Also, the bamboo stiffeners improved the ultimate load-carrying capacity of the beams by 15.7%, and increased the ultimate displacement and initial flexural stiffness by 10.13%.
