摘要
通过改进的粘结滑移试验装置 ,获得直径为 10mm和 16mm的 2种变形钢筋分别与高强混凝土 (HSC)和钢纤维高强混凝土 (FRHSC)的粘结滑移关系曲线 .在分析曲线特点基础上 ,重新定义了初始滑移量 ,提出双直线式的粘结滑移关系替代曲线 ,计算并分析了初始粘结应力、极限粘结应力。
The bond slip relationships between two types of bars ( d =10 mm,16 mm)and two types of concrete(HSC,FRHSC)have been gained with the improved device.Based on the curve characteristics,the initial slip has been redefined.The double line curve has been suggested to substitute the bord slip curve.The initial bond strength,the limited bond strength,and relationships between the bond slip and the concrete strength have been calculated and analyzed.
