摘　　要：根据适用于弯剪扭构件最小配筋率的界限条件,推导得出受扭钢筋最小配筋率的计算表达式。在一般房屋结构构件常用范围内,将计算结果与我国《混凝土结构设计规范》(GB50010—2002)的规定分析对比,并提出修改该规范有关条文的建议。Based on the limits situation of the minimum reinforcement ratio of reinforced concrete torsion-bending-shear members,the formulas for the minimum ratio of the torsion stirrup and the longitudinal steel of members were obtained.The results of the formulas were contrasted with Code for Design of Concrete Structures（GB50010—2002） within the range of common used building structural members.The proposal concerning modified formula of this code was presented.

关 键 词：弯剪扭构件 纯扭构件 受扭纵向钢筋最小配筋率
