摘　　要：重组竹不仅保留了原竹轻质高强、生态环保等优点,而且摒弃掉其原态性能不稳定、耐久性差等缺点,是一种理想绿色高强竹基材料,作为建筑材料引入现代结构中具有无可比拟的优势,符合国家大力发展竹产业、倡导节能减排的政策方针,应用前景广阔。然而现阶段重组竹结构的研究和应用明显滞后。基于此,归纳总结重组竹从制备、材料、构件、节点到结构体系的研究和发展现状,以层层递进的方式分析制约重组竹结构发展和应用的关键技术问题,为其后续研究指明方向。结果表明,重组竹结构基础研究不够深入,分散不成体系,已颁布实施的四部标准虽已初步构建起重组竹结构的技术标准体系,但试验和理论数据支撑尚显不足,条文多参考木结构规范而来,且均为团体标准,尚待进一步修正完善,进而建立起国家或行业标准。此外,现有研究集中于毛竹基重组竹,需进一步开展系统研究。The bamboo scrimber not only retains the advantages of light weight,high strength,ecological and environmental protection of the bamboo,but also abandons the disadvantages of unstable performance and poor durability.It is an ideal green bamboo-based material with high strength.The introduction of bamboo scrimber into modern structures as a building material has incomparable advantages,which is in line with the national policy of vigorously developing the bamboo industry and advocating energy conservation and emission reduction,and has broad application prospects.However,the research and application of bamboo scrimber structure lags behind apparently.Based on this,the research and development status of bamboo scrimber from the preparation,material,member,joint to structural system was summarized,the key technical problems restricting the development and application of bamboo scrimber structure in a progressive manner were analyzed,and direction for the subsequent research was indicated.The results show that the basic research on the bamboo scrimber structure is not deep enough,scattered and unsystematic.Although the four standards issued and implemented initially established the technical standard system for the application of bamboo scrimber structure,the support of experimental and theoretical data is still insufficient and most of the provisions are based on the wooden structure specifications.Besides,all four standards are group standards and need to be further revised and improved to establish national or industrial standards.In addition,the existing research focuses on the bamboo scrimber made from moso bamboo,and further systematic studies are needed.
