摘要
本文通过两个钢筋高强砼牛腿和5个钢纤维钢筋高强砼牛腿的试验,探讨了钢纤维高强砼牛腿在竖向力作用下的受力性能及破坏特征,提出了牛腿截面尺寸的计算公式;采用软化桁架理论为基础的极限承载力计算方法,其理论与试验结果符合较好.
Based on the test of two reinforced high-strength concrete brackets and five reinforced steel-fiber high-strength concrete brackets,the behavior and failure characteristics of REFHSC bracket under vertical Ioad are studied.A new method for determining the dimension of bracket and the ultimate load with the help of softened truss theory is proposed.The calculated values are in accordance with the test ones.
