The formulas to calculate the yield and ultimate curvature of beam are worked out considering the action of the stirrup, and the accuracy of the formula was proved by experiment.
提出屈服曲率和极限曲率(并考虑箍筋影响)的计算公式，与试验结果作比较，验证公式的有效性。

When HRB500 steel bars used as stirrup, the reinforced concrete beam may appear so oversized diagonal crack that it can't satisfy the engineering requirements for applicability and durability.
应用HRB500钢筋作为抗剪箍筋，可能会出现过宽的斜裂缝而不能满足结构的适用性和耐久性的要求。
