摘　　要：对5种不同钢纤维掺量下钢纤维钢筋混凝土的抗扭试验结果进行分析。在充分考虑钢纤维增强作用的同时根据复合材料力学法则,提出了钢纤维钢筋混凝土受扭构件的开裂扭矩和极限扭矩的计算公式。在公式的基础上,根据实际计算结果运用计算机进行拟合得出了钢纤维体积率在0.5%~2%之间的影响系数。提出的受扭公式与实际钢纤维钢筋混凝土受扭情况比较符合,从而为今后的研究提供了理论基础,具有一定的应用价值。The torsion test results of steel fiber reinforced concrete with 5 different content of steel fiber were analyzed.The calculation for- mula of cracking torque and ultimate torque of steel fiber reinforced concrete were given used compound material mechanics laws and taken the effect of steel fiber into consideration.According to the practical calculation results, the influence coefficient which the steel fiber volume rate is between 0.5%~2% fitted by using computer.Compared with steel fiber reinforced concrete torsion condition,the formula is more prac- tical,which can provide the theory for future research and to some extent has a certain application value.
