摘 要: 本文通过钢筋混凝土梁以及在受拉区部分地加入钢纤维的钢筋混凝土梁的试验及理论分析,研究了钢纤维混凝土层厚、钢纤维体积率和剪跨比对钢筋钢纤维增强部分混凝土梁受剪性能的影响,建立了与普遍钢筋混凝土梁受剪承载力计算公式相衔接的钢筋钢纤维增强部分混凝土梁受剪承载力的计算模型和计算公式. Based on the experiment and analysis of reinforced concrete beams and partial steel fiber reinforced concrete beams,the effect of the thickness of fibrous tensile zone,the volume fractions of steel fiber and the ratio of shear span to effective depth on shear behavior of partial steel fiber reinforced concrete beams are discussed.The model for calculation and corresponding formula are established which is complied with those of the conventional reinforced concrete beams.
