摘要 圆竹具有轻质高强、易于弯曲定型的特性,常用于建筑结构中,尤其是大跨度拱形结构这种具有曲线美感的建筑形式。文章以2019年北京世界园艺博览会竹藤馆为案例,通过实地考察和文献调研的方法,从原材料制备、建筑设计、节点构造、结构应力分散、拉结强化、装配式以及建筑健康监测等方面,综述了国内外较为经典的大跨度圆竹拱桥梁和建筑建造关键技术,分析了拱形建筑的受力特性以及圆竹材用于大跨度拱形建筑的材料适用性,提出标准圆竹材的应用在很大程度上延长了圆竹拱结构的寿命;构件预制化不仅降低了工程难度,还在一定程度上推动了竹建筑装配式进程;巧妙的节点构造和结构设计以及拉结强化均大大提高了竹建筑安全性;而后期健康监测和安全维护则进一步保证了大跨度圆竹拱建筑的安全性。本研究对圆竹标准材研究、圆竹拱形大跨度建筑技术体系建设、圆竹结构推广应用具有重要的学术参考价值,此外还具有重要的经济效益、社会效益。

Abstract:Round bamboo is characterized with high-strength, lightweight and easiness to bend, which is often used in architectural structures, especially in large-span arched structures with curved aesthetics. With an eye to the Bamboo and Rattan Pavilion at the International Horticultural Exposition 2019 Beijing China (Beijing Expo 2019), this paper summarizes the key technology used in classic large-span arched round bamboo bridges and buildings at home and abroad, and analyzes the force characteristics of arched buildings and the material applicability of round bamboo in large-span arched buildings by using field investigation and literature review, from the aspects of raw material preparation, architectural design, node structure, structural stress dispersion, tie strengthening, assembly and building health monitoring. It is pointed out that the application of standard round bamboo can greatly prolong the service life of arched round bamboo structure. Besides, the prefabrication of components not only reduces the engineering difficulty,but also promotes the assembly process of bamboo building to a certain extent. The ingenious node structure and structural design, as well as the pull knot strengthening greatly improve the safety of bamboo building, while the later- on health monitoring and safety maintenance further ensure the safety of large-span arched round bamboo building. This paper provides an important academic reference for the research on standard round bamboo material, the establishment of technology system for long-span arched round bamboo building and the extension and application of round bamboo structure, and achieves the important economic and social benefits.
