对东西南北4个不同方向的麻竹竹材的物理和力学性能进行分析,结果表明,不同方向的麻竹竹材的物理和力学性能之间存在一定的差异,但差异均不显著,说明东西南北各个方向对麻竹竹材的物理和力学性能均无明显影响。不同年龄的麻竹竹材的物理和力学性能之间也存在一定的差异,其中在各密度以及顺纹抗拉强度、抗压强度、抗弯强度和抗弯弹性模量方面,均表现为1.5龄>2.5龄>0.5龄;在各干缩率和顺纹抗剪强度方面,均表现为0.5龄>2.5龄>1.5龄。
The physical and mechanical properties of four different orientations of bamboo were analyzed. The results showed that there were some differences in the physical and mechanical properties of bamboo in different orientations, but the differences were not significant, indicating that each The direction of the bamboo bamboo physical and mechanical properties had no significant effect. There are also some differences between the physical and mechanical properties of bamboo of different ages, in which the density and the parallel grain tensile strength, compressive strength, flexural strength and bending elastic modulus, all showed 1.5 years > 2.5-year-old> 0.5-year-old. In terms of each shrinkage rate and shear strength, all showed 0.5-year age> 2.5-year age> 1.5-age.
