摘要
纤维增强塑料是一种高强、轻质、耐腐蚀、耐疲劳的新型复合材料,近年来,纤维增强塑料代替钢筋与预应力钢筋被广泛应用与混凝土结构之中,本文通过对12个150mm×150mm×150mm混凝土与GFRP筋粘结试件的试验研究,研究了GFRP筋直径及混凝土强度对粘结强度的影响,总结了粘结性能随埋长、纤维类型及表面形式的变化规律。
Fiber reinforcement plastic （FRP） is a new composite material of fatigue high- strength, lightweight, corrosion resistance. In recent years, fiber- reinforced plastics have been widely used to replace steel reinforcement and pre - stressed concrete strueturc. In order to investigate the bond behavior between GFRP rebars and concrete, twelve pullout specimens with the dimension of 150mm × 150mm × 150mm were cast and tested. The effects of concrete compressive strength, bar diameter on the bond behavior were investigated and the effects of anchorage length, fiber type and GFRP surface feature on the bond behavior were generahzed.
