摘　　要：为使竹材在桥梁领域上得到充分利用,本文通过设计抗拉和抗压两种新型竹结构连接节点,利用有限元分析和试验分析验证其应用于竹桥结构上的合理性。研究结果表明:新型竹节点的承载力满足人行竹桥的设计承载要求并且相比于构造相似的其他类型节点具有明显优势。本文成果可为建造以竹材料为主的竹桥提供一定的借鉴与参考。In order to make full use of bamboo in the field of bridges,two new connection nodes of bamboo structures,tensile and compressive,are designed,and the rationality of their application in bamboo bridge structures is verified by finite element analysis and experimental analysis.The research shows that the bearing capacity of the new bamboo nodes meets the design bearing requirements of the pedestrian bamboo bridge and has obvious advantages over other types of nodes with similar structures.The results can provide a certain reference for the construction of bamboo bridges based on bamboo materials.
