| 摘 要： | 通过中国混凝土结构设计规范与美国房屋建筑混凝土结构规范对单筋矩形截面的计算基本假定和砼受压应力图形的简化原则，推导出两种规范钢筋砼单筋矩形截面梁的配筋计算公式，通过各自的钢筋和砼保证率换算强度指标，分析比较两者在设计方法、设计参数取值上的不同，最后通过计算实例比较两者计算结果的差异。结果表明，荷载、梁截面尺寸、材料相同条件下，按美国规范计算出的钢筋砼单筋矩形截面梁的主筋比按中国规范计算出的钢筋砼单筋矩形截面梁的主筋多20．5％。

| Abstract: | The calculation formula for reinforcing bars of concrete beam is deduced according to the basic assumptions of Chinese codes for design of concrete structures and American building codes requirements for structural concrete,the differences between these two codes in design method and design parameters are analyzed,and the calculation results are compared based on a calculation example. |
