摘要
本文简单地分析了欧洲混凝土设计规范EN1992-1-1:2004规定的无腹筋混凝土梁斜截面抗剪承载力计算方法,对影响无腹筋梁斜截面承载力的因素如纵筋配筋率、剪跨比、混凝土抗拉强度等进行深入分析,对比了中欧规范不同考虑方式。通过比较分析,得到了中欧混凝土构件斜截面设计方法上的一些差异,也指出了中国规范未考虑纵向配筋率的影响。
The paper simply analyzes the European methods on the calculation of the shear strength without stirrups for the RC beams. The authors research the factors such as the reinforcement ratio, the shear span ratio, the concrete tensile strength etc, and compare the European formula with Chinese codes. The paper points out some design differences of the oblique sections based on the comparison.
