To take full advantages of the bamboo and cold-formed thin-walled steel, a new type of box section beam combined with bamboo and steel channel was proposed in this paper. Five composite beams with different parameters were tested to evaluate the effects of bamboo plywood thickness of composite beams and thickness and sectional dimension of steel channel. The results of experiment showed that the proposed composite beams exhibited excellent flexural bearing capacities and stiffness. The increase of bamboo plywood thickness and sectional dimension of steel channel could improve bearing capacity and flexural stiffness of composite beams, while the increase of steel thickness could enhance the bearing capacity and safety margin of composite beams. Furthermore, a new method to predict the deformation and bearing capacities of composite beams was proposed and matched well with the experimental results.

箱形截面竹钢组合梁的抗弯性能研究

为了充分利用竹板冷弯薄壁钢的优势,提出了一种新型的箱形截面梁与竹钢槽钢相结合的方案。测试了五种不同参数的复合梁,以评估复合梁的竹胶合板厚度以及钢槽道的厚度和截面尺寸的影响。实验结果表明,所提出的组合梁具有良好的抗弯承载能力和刚度。竹胶合板厚度和钢槽道截面尺寸的增加可以提高复合梁的承载力和抗弯刚度,而钢板厚度的增加可以提高复合梁的承载力和安全系数。此外,
