摘　　要：针对钢筋混凝土剪扭构件,从承载力计算公式、计算结果等方面,对我国《混凝土结构设计规范》(GB 50010—2010)和美国ACI318M-11规范进行分析对比,并对截面限制条件和箍筋最小配筋率进行比较。美国规范受剪扭承载力计算公式统一、简明,计算值与我国规范计算下限值接近,安全储备高于我国规范。我国规范剪扭承载力计算较为繁琐,有必要进一步简化和完善。Comparison of shear strength and torsional strength of RC member is studied between Chinese Code for Design of Concrete Structures （GB50010--2010） and American Code ACI 318M-11, including design methods, calculation methods, calculation results. The minimum section and minimum transverse reinforcement ratios in both codes are also compared. The results show that the formula for Shear Strength and torsional strength of American Code is unified and concise, and the design safety degree of American Code is higher than Chinese Code. It indicates that shear strength and torsional strength calculation is complex in Chinese code, and the modification should be further adopted.
