摘　　要：以混凝土结构整体为研究对象,以三铰拱为计算模型,以混凝土承压、钢筋承拉为配筋原则研究混凝土结构在受外力时连同支座的作用效应,并推算出配筋公式。通过与传统简支梁受弯配筋公式比较说明其适用性。This paper takes the whole concrete structure as study object,three-hinge arch as calculation model,concrete compression and steel straining as reinforcement principle,to study the action effect of concrete structure and the support under the external force and to deduct the reinforcement formula.This method was applicable compared to traditional simple-supported beam bending reinforcement formula.

关 键 词：钢筋混凝土结构 配筋 三铰拱
