[提要]  最小配箍率是保证钢筋混凝土构件不发生脆性破坏的重要构造措施。对《混凝土结构设计规范》( GB50010-2002)中保证钢筋混凝土受弯构件受剪承载力的最小配箍率计算进行了推导和分析，并与国内外规范进行了比较，结果表明，《混凝土结构设计规范》( GB50010-2002)的最小配箍率的计算规定是适宜的。

Minimum stirrups ratio is an important construction measure in order to refrain from brittle failure for RC members. We calculated and analyzed the minimum stirrups ratio for shear strength of RC member with bending in the new code ( GB50010-2002), and compared the analysis results with the code and the standards in many countries.  From the results, the calculation provision on mlnimum stirrups ratio in the new code is applicable.
Keywords:  concrete members;  shear strength; stirrups ratio; design code
