摘要：To meet the material requirements of a large span structural beam, a newly designed reinforced bamboo scrimber composite (RBSC) beam combining the bamboo element and the reinforcement element was developed. The RSBC beam was compared with other un-reinforced beams to evaluate its bending properties. Results indicated that the reinforcement and the bamboo elements could firmly form an integrated composite cross-section. The failure modes, ultimate load and cross-section stiffness of the RBSC beams were significantly correlated to the diameter of reinforcement as well as the heat treatment of bamboo bundle. A simplified mechanical model was also proposed according to the superposition principle, and the predicted deflection and load capacity matched well with the experimental results. This preliminary study is beneficial for the design, manufacture and application of bamboo-based structural composite materials in practical engineering. (C) 2017 Elsevier Ltd. All rights reserved.
