摘　　要：提出了通过合理配筋率与跨高比曲线关系来确定混凝土梁高的方法,解决了结构工程师在结构方案阶段无法较准确确定梁高的问题,使用GB 50010-2010混凝土结构设计规范中给出的考虑荷载长期作用影响的刚度计算公式,使得该方法理论依据更加合理,更加贴合实际工程,克服了根据经验值确定梁高的不足之处。The paper points out the identification method for the concrete beam depth by reasonable reinforcement ratio and span-depth ratio curve relation, solves some problems which can not be solved by the structural engineers at the structural scheme stage, adopts the stiffness calculation formula on the long term influence of the loading in GB 50010-2010 Design Regulation for Concrete Structure, so as to make the method＇ s theoret- ic reference more reasonable and close to the projects, and overcomes the defects of the beam depth by the empirical value.
