摘　　要：通过用我国《混凝土结构设计规范》、美国和欧洲规范对双筋矩形混凝土构件正截面受弯承载力进行对比研究。从结构设计方法、材料强度取值、正截面承载力计算方法、最大和最小配筋率、受弯承载力计算结果进行了全面的正截面受弯对比分析。结果表明,在适筋范围内,美国规范的最小配筋率比我国规范以及欧洲规范都要高;此外在设计方法、受弯承载力等方面都有所不同。The adoption of code for the design of concrete structures in China, the United States and the European codes for double reinforcement rectangle comparison of flexural bearing capacity of normal cross section of concrete. From structural design, material strength value, normal section bearing capacity calculation method, maximum and minimum reinforcement ratio, calculation oftlexural bearing capacity of bending normal results with comprehensive analysis.The results showed that the minimum reinforcement ratio in the united states is higher than China and European in the reinforced area.in addition,there are different between in the design method and bending bearing capacity.

关 键 词：受弯承载力 最小配筋率 混凝土结构设计规范 欧洲规范 美国规范
