【摘要】 和高强、轻质、耐腐蚀的 GFRP 筋相比,GFRP/钢绞线复合筋的弹性模量较高,并具备了一定的屈服特性,克服了 GFRP 筋的脆性。为了增强 GFRP/钢绞线复合筋与混凝土的粘结,需对 GFRP/钢绞线复合筋的肋参数进行定型。本文利用拉拔试验研究肋间距对 GFRP/钢绞线复合筋与混凝土的粘结性能的影响,并与钢筋和混凝土的粘结性能进行比较。最后基于粘结性能优劣的评价准则,确定 GFRP/钢绞线复合筋的最佳肋间距,为 GFRP/钢绞线复合筋的生产和工程应用提供参考。
【Abstract】 With comparison to GFRP rebar,GFRP/steel wire composite rebar has superior mechanical properties, such as high tensile strength,strong resistance to corrosion,high elastic modulus,yield characteristics and so on. This paper presents test results of the experimental study on rib geometries determination of GFRP/steel wire composite rebars.Pull-out test was used to study the bond behavior of GFRP/steel wire composite rebars to concrete.For each rebar,the bond strength and the slip at the loaded end were obtained,and the corresponding bond-slip relationship curves were analyzed.Using the optimum criterion,design recommendations were made concerning optimum rib geometries of GFRP/steel wire composite rebars with superior bond-slip characteristics
