摘要
对GB50010-2002《混凝土结构设计规范》斜截面受剪承载力设计公式用于多种载荷作用下的情况进行研究,分析现有公式存在的问题。在此基础上,对比分析各国受剪承载力设计公式的特点。研究结果表明,在多种载荷作用下采用我国规范受剪承载力设计公式,会造成配箍率的不连续,我国设计公式在国际上尚处于较低水平,建立一个统一的受剪承载力设计公式,是一个有待研究的内容。
According to the GB 50010-2002 《Design Code of Concrete Structures》,shear capacity of oblique section of RC beams is calculated by using two different formulas under various loads.The problem which is caused by using different formulas has been analyzed.Moreover,comparison for shear capacity between Chinese and foreign codes has been discussed.From the results it can be seen that the stirrup ratio which is calculated by our design code is discontinuous,and the formula for the shear capacity of our country is still fairly low.Therefore,establishing a unified formula is to be studied.
