对15个重组竹顺纹销槽承压试件和15个重组竹横纹销槽承压试件进行单调加载试验,采用位移控制法加载直至破坏,研究销槽的极限承压强度。试验结果表明,顺纹销槽承压试件的极限承压强度平均值为91.59MPa,呈现明显的脆性破坏特征,试件刚度较大;而横纹销槽承压试件的极限承压强度平均值为71.81MPa,其变异系数达到0.143 2,最大位移均在10mm左右,表现出较好的延性,试件刚度也明显较小。
Fifteen reorganized bamboo parallel grooved groove test specimens and 15 reorganized bamboo straight grooved groove test specimens were subjected to monotonous loading test. The displacement control method was adopted to load until failure. The ultimate bearing strength of the groove was studied. The test results show that the average compressive strength of the cross-groove groove bearing specimen is 91.59MPa, showing obvious brittle failure characteristics, and the specimen rigidity is large. The ultimate compressive strength The average value is 71.81MPa, the coefficient of variation is 0.143 2, the maximum displacement is about 10mm, showing good ductility, the specimen stiffness is also significantly smaller.
