摘要
通过钢纤维高强混凝土切口梁三点弯曲试验,探讨了钢纤维掺量对高强混凝土断裂能、断裂韧度的影响。结果表明:随着钢纤维掺量的增大,高强混凝土断裂能、断裂韧度均逐渐增加。在分析试验结果的基础上,建立了钢纤维掺量与高强混凝土断裂能、断裂韧度间的统计关系式。
Through the three-point bending test on the specimens of steel fiber reinforced high strength concrete（SFHSC）,the effect of the fiber volume fraction（ρf） upon fracture energy and fracture toughness were studied.The results show that fracture energy and fracture toughness increases with the increase of ρf.Based on the test results,Statistical relationships have been established between ρf and fracture energy and fracture toughness of SFHSC.
