摘要
对上海世博会德中同行亭的竹结构体系及其特点作了介绍。进行了竹材顺纹抗拉试验和按实际设计长度进行天然竹竿构件的抗压抗拉承载力试验,得出了竹材弹性模量和各种长度的构件极限承载力及破坏模式,并比较了构件稳定折减系数试验值和理论计算值。建立整体空间结构模型进行计算和分析,研究了构件的内力、结构的振动特性、结构的变形及结构的稳定极限承载力,论证了结构的可靠性及安全性,并对构件的端部节点设计作一介绍,为今后类似的竹结构工程提供参考借鉴。
The bamboo structural system and characteristic of Shanghai Expo Special Project DuC are introduced.From the material tension testing to grain of the bamboo and the natural bamboo member testing based on the precise projected dimension,the Young＇s modulus,the ultimate bearing capacity and damage modes of members with different length were obtained.According to the calculation and analysis of the spatial structural model,the contents including the inner forces of the members,the structural vibration characteristics,deformation,and the ultimate bearing capacity were analyzed,which verified that demonstrating the structure is stable and safe,and the joint design of the member was introduced.It can be used as a valuable reference for the design of similar structures.
