摘要:
以毛竹圆竹和竹片为研究对象，研究其顺纹方向的力学性能.通过41个试件的试验研究，获得了毛竹竹片顺纹方向的弹性模量、抗压强度、抗拉强度以及毛竹圆竹顺纹方向的抗压强度和抗剪强度等力学指标，所有强度计算结果转化成含水率为12% 时的强度，以消除含水率差异的影响.结果表明：竹材顺纹抗拉强度略大于抗压强度，以圆竹和竹片为测试单位测得毛竹竹材的顺纹抗压强度相差不大，竹节对竹材的抗压强度提高不明显，对抗拉强度和抗剪强度有所削弱.研究还提出了试件破坏现象及原因，为竹结构房屋设计与进一步理论分析提供必要依据.
Abstract:
The experiment was conducted to study the mechanical properties of Moso bamboo culms and bamboo sheets along the grain direction. This enable us to know we know the elastic modulus, the compressive strength, tensile strength and shear strength of the bamboo along the grain direction through the study of 41 specimens. All the strength was converted to when moisture content is 12%, to eliminate the effects of moisture content differences. The results show that the tensile strength of bamboo is slightly larger than compressive strength along the grain direction. The compressive strength is almost equal when it was tested as bamboo culms and bamboo sheets. The bamboo node rarely improved the compressive strength, and weakened the tensile strength and shear strength obviously. This research also proposed the phenomenon of specimens failure and the reasons, provided necessary basis for the bamboo structure housing design and further theoretical analysis.
