摘要
以毛竹圆竹为研究对象,研究其力学性能的变异规律。结果表明:以圆竹为测试单元毛竹各项性能测试结果不同于以竹片为测试单元测得的结果,但是毛竹圆竹的各项力学性能在竹龄、竹秆部位上的变异规律和竹片力学性能的变异规律相似。随竹秆高度的增加,其纵向抗压强度、纵向抗剪强度、抗弯强度均呈增大趋势;4年生毛竹的力学性能总体优于6年生毛竹。
An experiment was conducted to study the mechanical properties of Moso bamboo-culms. It can be found that the test results of bamboo-culms differed from bamboo sheets, but the variation laws of mechanical properties between bamboo-culms and bamboo sheets were similar at bamboo age and stem position. As the height of the eulms increased, the longitudinal compressive strength, longitudinal shear strength and bending strength showed an increasing trend; the mechanical properties of 4-year-old Moso bamboo were better than that of 6-year-old.
