摘要
论述了34个钢纤维砼和普通砼试件,在单调、重复和反复荷载下,与变形钢筋的粘结锚固性能的试验结果.试验表明,钢纤维砼具有较高的粘结强度,并可减小钢筋的滑移.在分析试验结果的基础上,提出了关于钢纤维砼粘结强度计算公式和钢筋设计锚固长度的建议.
This paper describes the experiment of bond behavior of 34 specimens,of which 22 are steel fiber concrete(SFC) and 12 are conventional concrete,under monotonic,repeated and reversed cyclic loading.The results show that the specimens with steel fibers have better strength and less bond- slip than conventional concrete.Based on the analyses of the experimental results,an equation for calculating the bond strength of SFC and the proposal for describing the bar anchorage length are presented.
