[提要]  最小配箍率是保證鋼筋混凝土構(gòu)件不發(fā)生脆性破壞的重要構(gòu)造措施。對(duì)《混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范》( GB50010-2002)中保證鋼筋混凝土受彎構(gòu)件受剪承載力的最小配箍率計(jì)算進(jìn)行了推導(dǎo)和分析，并與國(guó)內(nèi)外規(guī)范進(jìn)行了比較，結(jié)果表明，《混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范》( GB50010-2002)的最小配箍率的計(jì)算規(guī)定是適宜的。

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
