摘　　要：GB50010-200x《混凝土结构设计规范》(征求意见稿)对矩形截面钢筋混凝土框架柱双向受剪承载力计算公式进行了修正,修定后的公式仅对由混凝土提供的双向受剪承载力进行了折减。本文通过7根加载角度不同的矩形截面框架柱在斜向水平荷载作用下的受剪承载力试验,探讨修订公式计算矩形截面框架柱双向受剪承载力的可行性,试验结果和计算值的对比表明,修正后的公式可以安全计算矩形截面框架柱双向受剪承载力,而且具有一定的精度。The formulas to predict the bilateral shear strength of rectangular frame column（RFC） were modified in Code for Concrete Structure Design（GB50010-200x,consultive paper） and the bilateral shear strength contributed by concrete was reduced in the revised formulas shown in the code.To disscuss the feasibility that the bilateral shear strength of RFC was estimated by the revised formula,a total of 7 RFC subjected to oblique horizontal load with various loading angle were experimented.The comparisons between experimet results and predictions shown that the bilateral shear strength of RFC can be evalucated safety by the revised formula and the predictions have a good consistency with experiment results.
