摘　　要：工程竹材具有高强度、高耐候性、高尺寸稳定性以及强耐腐性等优点。随着人们对工程竹材的开发利用,工程竹材在建筑、家具、运输等领域得到广泛应用,其节点连接性能的研究是现代竹木结构质量与安全的重要保障。该文从工程竹材的基本力学性能和节点连接性能2个方面对工程竹材研究进行综述。阐述了工程竹材在抗压、抗弯和抗剪3种基本受力形式下的力学行为及提高工程竹材承载性能的措施。分析齿板连接、螺栓连接、金属套筒连接对工程竹材承载性能、破坏模式以及受不同参数的影响规律。对国内外几种木结构设计规范相关计算理论所存在的误差进行总结,指出需要尽快制定工程竹材的标准规范,以期推动工程竹材的进一步应用发展。Engineered bamboo has the advantages of high strength, high weather resistance, high dimensional stability and strong corrosion resistance. With the continuous development and utilization of engineered bamboo, it has been well applied in construction, furniture, transportation and other fields. The study on the joint performance is an important guarantee for the quality and safety of modern bamboo and wood structures. The research progress of engineered bamboo was summarized from the basic mechanical properties and joint connection performance. The three basic stress forms of compression, bending and shear of engineered bamboo and measures to enhance the bearing capacity of engineered bamboo were elucidated. The effects of tooth plate connection, bolt connection and metal sleeve connection were analyzed based on the bearing capacity, failure mode of engineered bamboo and the laws affected by different parameters. The errors were summarized in the relevant calculation theories of wood structure design specifications at home and abroad. Results suggest it is necessary to formulate the relevant standards and specifications of engineered bamboo as soon as possible, in order to promote the further application and development of engineered bamboo.
