Steel-bamboo composite beams were fabricated with cold-formed thin-walled steel and bamboo plywood bonded by structural adhesive. Six specimens were tested to investigate the effect of the steel-bamboo interfacial slippage on the deformation of the composite beams. Assuming interfacial shear force is proportional to the slippage; differential equations were established to relate deformation with the arbitrary loads, based on the elementary beam theory, and the differential relationship between the interfacial slippage and the strain. The mid-span deflection equations were derived considering the slipping effects of three common load cases. Comparing the theoretical deflections with and without the effect of slippage to the experimental results, the accuracy was improved by 7%. It was found that the interfacial bond stiffness has significant influence on the deformation of the steel-bamboo composite beams. When bond stiffness was up to a value of 700N/mm, it could ensure a reliable composite bonding between the steel and the bamboo plywood. The finite-element software ANSYS was then employed to validate the analytical results. Spring elements COMBIN39 were used to model the interfacial adhesive. The results were in good agreement with those obtained from the experimental and theoretical analyses.
