[提要]  介绍了此次《混凝土结构设计规范》修订中纵向钢筋最小配筋率有关条文的修订背景。其中着重说明了构件中受拉和受压纵向钢筋最小配筋率在非抗震结构及抗震结构中所起的作用及其取值思路；在对国外规范相应规定进行对比分析的基础上，对我国修订后规范最小配筋率取值水平作了判断；并对一些遗留问题进行了讨论，给出了相应的建议。

Background to provisions in Cocle for cleszgn o[concrete structures with regard to minimum longitudinal reinforcement ratio in RC members is presented.  The function and evaluation of mlnlmum longitudinal reinforcement ratio both under compression and tension are analysed. On the basis of comparison with foreign codes, discussions on the level of evaluation of minimum reinforcement ratio in the revised code are given, along with other remaining problems.
Keywords: reinforced concrete; reinforcement detailing; minimum longitudinal reinforcement ratio
