摘  要：
为了提高竹结构在建筑结构领域的使用性能,提出一种新型嵌入式钢筋增强竹梁,利用嵌入式技术将钢筋嵌入竹梁的受拉区进行竹梁增强,通过4根钢筋增强竹梁及4根对比竹梁的试验研究发现,竹梁增强后其刚度得以改善,但设计荷载仍然是由其截面刚度控制,钢筋的配置分担了受拉区竹材的拉应力,嵌入式钢筋增强竹梁其最大优势在于绿色、低碳、节能、减排,为其大规模推广应用成为可能。

摘  要：
In order to further improve the performance of bamboo structures in the area of construction,a type of bamboo beams reinforced with near surface mounted steel bars was proposed in the paper.The experimental study on four bamboo beams with and without steel bars strengthening was conducted.Results show that steel bars can effectively enhance the stiffness of bamboo beams,but the design load is still controlled by the stiffness of its cross-section,and the steel bars in the tension zone share tensile stress of bamboo.The greatest advantages of the bamboo beams reinforced with near surface mounted steel bars is green,low carbon,energy saving and can reduce carbon dioxide emissions,making its large-scale popularization and application possible.
