钢筋混凝土结构的损坏,多由钢筋锈蚀引起。要使钢筋免于锈蚀,目前还没有绝对可靠的方法。采用非锈蚀的玻璃纤维增强塑料筋取代普通钢筋,就从根本上消除了钢筋被锈蚀的隐患。美国麦克金利维尔大桥是一座横跨布法罗河的公路桥,混凝土桥面板中率先采用了玻璃纤维增强塑料筋 Reinforced concrete structure damage, mostly caused by corrosion of steel. There is no definitive method for reinforcing steel bars from corrosion. The use of non-corrosive glass fiber reinforced plastic instead of ordinary steel reinforcement, it is fundamentally eliminate the risk of corrosion of steel. The United States McKinleyville Bridge is a highway bridge across the Buffalo River, the first concrete deck bridge using glass fiber reinforced plastic
