摘要
基于拉拔和梁式试验 ,探讨了这两种试验方法对GFRP筋与不同种类混凝土 (包括混凝土C30、掺纤维与不掺纤维的混凝土C5 0等 )之间粘结强度的影响。研究表明 ,梁式试验的GFRP筋粘结强度稍低于拉拔试验的结果 ;混凝土强度等级以及是否掺加聚丙烯纤维对GFRP筋的粘结强度影响较小。
Based on 18 pull-out tests and 18 bean tests,the influence of the two methods on bond strength of GFRP rebars with different concrete (including concrete C30,concrete C50 with and without polypropylene fibers) is studied in detail.The study shows that the bond strength of beam specimens is a little less than that of pull-out specimens and influence of the concrete strength and polypropylene fibers is much less.
