摘　　要：推导了部分预应力钢筋混凝土受弯构件的最小配筋率计算公式,并结合我国各行业规范对非预应力钢筋最小配筋率的规定,对部分预应力梁中的HRB500级钢筋的最小配筋率提出建议,为将HRB500级钢筋列入我国混凝土结构设计规范提供参考。The calculation formula of the least ratio of the nonprestressed reinforcement in partially prestressed concrete beams with HRB500 steel bar is deduced.And some suggestions on the least ratio of the nonprestressed reinforcement in partially prestressed concrete beams with HRB500 steel bar are proposed based on each industry standard of the least ratio of the nonprestressed reinforcement at home.Which provided a reference for using HRB500 steel bar in China code for design of concrete structures.

关 键 词：HRB500级钢筋 部分预应力钢筋混凝土梁 受弯构件 脆性破坏 最小配筋率
