摘 要: 根据试验研究结果以及钢纤维混凝土的应力应变关系特点 ,建立钢筋钢纤维混凝土深梁斜截面破坏模型 ,并运用塑性分析方法建立与普通钢筋混凝土深梁相衔接的统一的斜截面受剪承载力的塑性计算公式 ,该公式与试验数据符合较好 . Based on the experimental results and the characteristic of stress-strain relationship of steel fiber reinforced concrete, the diagonal sectional failure mode of steel fiber reinforced concrete deep beams is established. With the plastic ultimate analysis, the unified calculating formula is researched, which is connected with that of normal reinforced concrete deep beams and fits the experimental data well.
