摘　　要：文章简要介绍了国内外对原竹、圆竹结构的发展史和研究现状;概括总结了两种结构用胶合竹材的研究进展,并对以胶合竹为基础的现代竹结构的研究现状做了深入分析。结果表明,目前国产结构用胶合竹材存在诸多不足,胶合竹结构的抗火、抗震等关键物理和力学性能还需进一步深入研究。目前,缺乏竹结构设计规范是限制新型胶合竹结构发展的主要原因,文章建议进一步开展胶合竹材力学模型的研究,建立胶合竹材的本构关系,为未来胶合竹结构的深入研究和设计规范的编写提供理论支撑。This paper briefly introduces the research and development of bamboo material and round bamboo structure at home and abroad, also, the research of two kinds of glued laminated bamboo for structure use are summarized. An in-depth analysis of the research status of modern bamboo structure based on glued laminated bamboo. The results show that there are still many deficiencies used of the structural glued laminated bamboo produced domestically, and some important physical and mechanical properties of modern bamboo structure need further study such as fire and seismic resistance. At present, the lack of design specifications for bamboo structures is the main reason for restricting the development of newly developed bamboo structures based on glued laminated bamboo. It is suggested that a series of further researches should be done on the mechanical model of glued laminated bamboo so as to establish its constitutive relationship, which can be the theoretical support for future research of modern bamboo structures and the preparation of design specifications.
