作为既有钢桥经常出现的疲劳裂缝的一种修复方法,碳纤维增强塑料(CFRP)加固带是一种先进的预应力体系。疲劳试验结果表明,该系统大大提高了修复后的疲劳寿命。在此基础上,提出了外贴碳纤维布修复疲劳裂纹的疲劳寿命预测和耐久性提高方法。
英文摘要
As a repair method of fatigue cracks, which are often initiated in existing steel bridges, an advanced prestressing system by externally-bonded CFRP (Carbon Fiber Reinforced Plastic) strips. The result of fatigue tests shows that the fatigue life after repair is drastically improved by using the developed system. Moreover, the methods of fatigue life prediction and the durability enhancement in the fatigue crack repair using externally-bonded CFRP strips were proposed.
