现代竹结构的研究现状和展望

THE STATE OF THE ART OF MODERN BAMBOO STRUCTURES

现代竹结构是一种新型的结构体系,相比于钢结构和混凝土结构体系,其最大的不同在于采用天然竹材为原材料,与北美等工业化国家和地区广泛使用的木结构类似,更加低碳、环保。现代竹结构主要采用现代胶合技术使空心圆竹成为基于竹纤维的复合材料,从而适合采用类似现代木结构的设计和施工方法,且材料和结构性能可以通过现代试验方法进行检测验证。国内外不少研究者在现代竹结构的研究方面做了比较系统的工作,现代竹结构作为一种新型结构体系的轮廓逐渐显现。通过分析该体系的发展过程,总结相关研究内容,对现在竹结构体系在装配式活动板房、轻型竹结构房屋、大空间框架体系和桥梁方面的应用实例进行介绍,并对现代竹结构的发展现状及其优缺点进行分析和总结。现代竹结构的发展进展表明现代竹结构体系在土木工程这一领域将大有可为。

Modern bamboo structure is a new kind of structural system, receiving more and more attentions in today＇s move towards sustainable construction.Comparing with conventional systems, such as steel and concrete structures, the modern bamboo structural system is based on the natural bamboo as raw materials.Similar to but even better than timber materials, bamboo is a carbon negative material.Modern bamboo structure is essentially a bamboo fiber-based composite material, adopting similar forms as modern wooden structures which are widely used in industrialized countries.A systematic research work was done by domestic and overseas researchers in modern bamboo structures, through which the modern bamboo structure system was gradually shaping.This paper analyzed the development of the system, and summarized the research progress, and finally, some application demonstrations of modern bamboo structures in prefabricated movable house, light bamboo house and large-space frame system etc were described. Clearly, it is shown that modern bamboo structure system will have bright prospects in near future and at least is an alternative choice for consideration of sustainability.
