摘要:
使用计算机控制的电液伺服压力机，对63个钢纤维混凝土圆柱体试件进行单轴压缩试验，研究钢纤维类型、掺入率与混凝土强度等级对钢纤维混凝土单轴受压性能的影响。结果表明：掺入一定量的钢纤维可以有效提升混凝土的抗压强度，但提升幅度随着混凝土强度等级的增大而减小。在CF50强度等级时，多锚固点型钢纤维对混凝土抗压强度的影响明显高于剪切型钢纤维，但韧性指数低于剪切型钢纤维；CF30和CF40强度等级下，两种钢纤维对混凝土抗压强度的影响相似，多锚固点型钢纤维对混凝土的增韧效果较剪切型钢纤维要好。根据试验结果修正了不同类型钢纤维混凝土抗压强度的计算公式，通过与试验结果对比验证了其合理性。
Abstract:
The uniaxial compressive experiment of steel fiber reinforced concrete cylinder was carried out by microcomputer controlled electro-hydraulic servo pressure testing machine, which studied the effects on types of steel fiber, fiber volume fraction and concrete strength grade to uniaxial compressive behavior of steel fiber reinforced concrete. The results show that steel fiber reinforced concrete can efficiently enhance the concrete compressive strength, but the range of concrete strength grade will decrease with the increase of concrete strength grade. In strength grade of CF50, the compressive strength of multi-anchor point fiber reinforced concrete is obviously higher than the compressive strength of shear type fiber reinforced concrete, but the toughness index of multi-anchor point fiber reinforced concrete is lower than the toughness index of shear type fiber reinforced concrete. In strength grade of CF30 and strength grade of CF40, there are similar effects on the two kinds of steel fibers to the concrete compressive strength, but the toughening effect on multi-anchor point fiber reinforced concrete is better than the toughening effect on shear type fiber reinforced concrete. According to the test results, the formulas for calculating the compressive strength of different types of steel fiber reinforced concrete (SFRC) are modified and their rationality is verified.
