摘要

摘要: 通过对27个拉拔试件和16个梁式试件的试验,探讨AFRP筋与混凝土的粘结滑移关系、粘结强度,并且综合分析其他文献的结果,提出简化的局部粘结滑移本构关系和拔出破坏模式下锚固长度的计算公式。

Abstract: Based on tests of 27 pull-out specimens and 16 beam specimens,the bond-slip relation and bond strength between AFRP bars and concrete are discussed.And according to other references of the experimental result,the simplification of local bond-slip constitutive relation and a calculation formula of anchorage length of AFRP bars with pullout failure are obtained.
