【摘要】 通过 18根 12 0 0mm× 760mm× 40 0mm的混凝土拉拔试件和 64根 12 60mm× 2 40mm× 15 0mm的混凝土梁式试件的试验 ,研究了纤维聚合物筋与混凝土的粘结性能 ,获得了大量的试验结果。以这些试验数据及有关文献报道的相关的试验结果为基础 ,探讨了破坏形式、混凝土强度、锚固长度、纤维聚合物筋直径、混凝土浇筑深度、环境条件等因素对粘结性能的影响。结果表明 ,上述因素对纤维聚合物筋与混凝土的粘结性能有一定的影响 ,在锚固长度等有关的计算中应适当考虑更多还原

【Abstract】 In order to investigate the bond properties of FRP rebars to concrete,eighteen pullout specimens with the dimension of 1 200 mm×760 mm×400 mm and sixty four beam specimens of 1 260 mm×240 mm×150 mm were cast and tested.The extensive experimental results were obtained.Based on these results in conjunction with those selected from the pertinent literature,the objective of this paper is to investigate the effects of the failure mode,concrete compressive strength,anchorage length,bar diameter,concrete cast depth,environmental condition etc.on the bond properties.The experimental results showed that these factors mentioned above have much effect on the bond properties of FRP rebar to concrete,and it is necessary to account for their influences in the calculation such as the length.更多还原
