Test Study on Bond-slip Relationship between C80 High Strength Concrete with Deformed Reinforcing Bar
Author(s): 
Pages: 714-718
Year: Issue:  6
Journal: JOURNAL OF TONGJI UNIVERSITY(NATURAL SCIENCE)

Keyword:  高强混凝土普通混凝土粘结滑移关系;
Abstract: 通过改进的粘结滑移试验装置,获得直径为10 mm和16 mm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、粘结滑移与混凝土强度的关系.
