摘　　要：为比较钢筋砼构件采用中美规范设计计算结果,首先取相同的材料按各自的取值方法、试验方法换算出各自的材料指标,分析比较两本规范在设计参数取值上的不同,推导出中国常用的钢筋和砼按美国规范取值强度指标的换算公式,计算出中国常用钢筋和砼等级按美国规范取值的的强度指标。再通过两本规范的基本假定、荷载组合和设计表达式,推导出矩形截面梁的纵筋、箍筋以及大偏压柱纵筋计算公式,分析比较两本规范在设计方法的区别,最后通过计算实例比较两本规范梁、柱配筋计算结果的差异。To compare the calculations of reinforced concrete components by use of Chinese code and American code,this paper firstly takes the same material at the respective value method and test method to convert into their respective material indicators,and then analyzes and compares the differences in design parameters taken in these two codes to ?? derive the conversion formula of strength index value for China commonly used steel bar and concrete according to U. S. specification values. Then through the basic assumptions,load combinations and design expressions of the two codes,this paper deduces the calculation formulas for longitudinal bar and stirrup of rectangular beam and large bias column longitudinal reinforcement. This paper also analyzes and compares the difference in the design methods between the two codes,and finally compares the calculation differences of beam and column reinforcement between the two codes through calculation examples.
