钢纤维混凝土梁的抗剪强度

Shear Strength of Steel Fiber Reinforced Concrete Beams

实验研究表明：钢纤维可提高钢筋砼梁的抗剪强度，并能与箍筋协同作用形成一有效的抗剪钢筋体系。根据实验结果，导出一个预测无腹筋钢纤维砼梁的抗剪强度经验回归公式。此式能较好地预测梁的抗剪强度。

The experimental studies have shown:the steel fiber can be used to increase the shear strength of reinforced concrete beam and can combine with stirrup to subject shear force. According to experimental results,an empirical relationship is suggested for predicting the ultimate shear strength of fiber reinforced concrete beams without web reinforcement. The proposed relationship is compared well with the reported test results in literature.
