SHEAR STRENGTH OF REINFORCED CONCRETE BEAMS WITHOUT WEB REINFORCEMENT UNDER CONCENTRATED LOAD
-
摘要: 根据对国内外343根钢筋混凝土无腹筋梁在集中荷载作用下的试验数据,分别用混凝土轴心抗压强度fc、混凝土抗拉强度ft和fc建立了无腹筋梁受剪承载力平均值的计算公式;并对现行规范无腹筋梁受剪承载力的可靠度进行了分析;最后提出了用fc表达的钢筋混凝土无腹筋梁受剪承载力计算公式。Abstract: According to the experimental data on 343 reinforced concrete beams without web reinforcement under concentrated load,formulas to calculate the mean shear strength of reinforced concrete beams without web reinforcement respectively with f_c,f_t and f_c had been established.The degree of reliability of the current code in calculating the shear strength of reinforced concrete beams without web reinforcement had also been discussed.Then a formula expressed by f_c to calculate the shear strength of reinforced concrete beams without web reinforcement had been given.
