原竹建筑竹木套接-木木榫卯节点连接方式研究

Study on Bamboo Buildings of Bamboo - wood Cup Joints with Wooden Tenon - mortise Joints

竹材有较高的抗拉与抗压强度,良好的弹性与韧性,且节能环保,而以原竹为结构材料的原竹建筑在现代社会的应用却鲜有其例,一个重要的原因就是缺乏牢固可靠耐久的连接方式.为了突破原竹建筑发展的瓶颈,提出了竹木套接-木木榫卯的节点连接方式,对节点进行了构造设计与分析,并通过对一栋两层框架原竹建筑的算例的整体结构的Etabs设计计算及其中节点的Abaqus有限元分析,论证了此种连接方式的安全性与可行性.

The bamboo material not only has a high tensile and compressive strength,good flexibility and toughness,but also is energy-efficient and environmental.But the application of bamboo buildings which use bamboo as structural material is rare.One important reason is the lack of a solid,reliable and durable connection.In order to break through the bottleneck of the bamboo buildings development,this thesis proposed the connection of bamboo-wood cup joints with wooden tenon-mortise joints,and designed and analyzed the structure of node through Etabs designing and calculating of an example of two-story framework bamboo building.Through the finite element analysis of its intermediate node with Abaqus,the safety and feasibility of this connection were proved.
