竹重组材连接力学性能试验研究文献综述

摘要:竹重组材是竹材未来最具发展前景的高效利用途径之一。随着竹材的发展与应用,越来越多的构件甚至建筑开始使用竹重组材。这些构件、建筑在外荷载的作用下其连接节点处往往会承受较大的弯矩和剪力,需要较大的刚度才能满足设计和使用要求,这时候传统的榫卯连接和普通销式等金属连接件连接已无法满足要求。螺栓连接、齿板连接等连接具有可靠、美观和易安装等优点,而且还拥有较高的承载力和较好的延性,现已经被广泛的运用于构件建筑的连接中。连接构件中最重要的部位就是其节点处,本文是对部分竹材连接力学性能试验研究文献概述,首先介绍了竹材这种材料的特性,接着概括了国内外研究竹材连接结构的一个研究现状,然后是列举部分竹材构件的连接形式以及对其连接构件的力学性能试验的综述,最后是研究的目的和意义以及对未来研究发展的建议。

Review of experimental research on mechanical properties of Bamboo Reconstituted material

Abstract: Bamboo Reconstituted material is one of the most promising and efficient utilization ways in the future. With the development and application of bamboo, more and more components and even buildings begin to use bamboo composite. Under the action of external load, the joints of these components and buildings often bear large bending moment and shear force, which requires large rigidity to meet the design and use requirements. At this time, the traditional mortise and tenon connection and ordinary pin type metal connection cannot meet the requirements. Bolt connection, tooth plate connection and other connections have the advantages of reliability, beauty and easy installation, and also have higher bearing capacity and better ductility, which have been widely used in the connection of component buildings.The most important part of a connecting component is its nodes.This paper is an overview of the experimental research literature on the mechanical properties of some bamboo connections. Firstly, it introduces the characteristics of this material, and then summarizes the research status of the bamboo connection structure at home and abroad. Then, it lists the connection forms of some bamboo components and summarizes the mechanical properties of the connection components. Finally, it is the purpose and significance of the research and the future research and development Suggestions for the exhibition.

中国古代大多使用竹木结构作为建筑的主要体系,但大部分的建筑是木结构。然而随着社会的进步和人类的发展,竹木结构建筑不能够满足现代建筑的要求,从而出现了钢材、混凝土等新的建筑材料和建筑体系。如今,“绿色环保”成为环保、低碳的可持续通道的必经之路,如何在确保建筑安全、可靠和舒适的使用性能的基础上实现环境的友好,成为全社会正在思考的重要问题,而现代竹木结构体系的出现,给我们提供了一种很好地选择。
