摘　　要：基于钢-混凝土组合梁竖向抗剪试验,探讨了组合梁中钢梁承担的剪力,总结了组合梁受剪的特点,分析了剪跨比、钢梁截面尺寸、混凝土翼板截面尺寸和抗剪连接程度等因素对组合梁受剪承载力的影响。采用叠加法,提出了组合梁受剪承载力计算公式,该公式物理意义明确,简单实用,与试验结果符合较好。On the basis of vertical shear experiments of steel-concrete composite beams, shearing force of steel beams in the composite beam is discussed, and characteristic of composite beam enduring shear is summarized. Several factors which influence shear capacity of composite beams are analyzed, such as shearing-span rate, sectional dimension of steel beams, sectional dimension of concrete flange plate and the degree of shear connection. Superposition method is adopted to provide a calculating formula for composite beams. The formula has definitive physical meaning, is simple, practical, and the calculations are in good agreement with the tests.
