摘要
纤维增强复合材料(FRP)在土木工程中作为一种具有强度高、耐腐蚀、质量轻等优点的新型高性能复合材料受到了广泛应用。FRP筋与钢筋混杂配筋可解决钢筋混凝土结构中的钢筋锈蚀问题及FRP加筋混凝土结构挠度大、裂缝过大问题。本文介绍了FRP-钢筋混杂配筋混凝土梁在两种界限破坏时的配筋率,提出了混杂配筋梁在不同配筋率时的破坏形式判别方法。
Fiber-reinforced polymer composite material(FRP)has been widely used in civil engineering as a new type of high-performance composite material with advantages such as high strength,corrosion resistance and light weight.The hybrid reinforcement of FRP bars and steel bars can solve the problem of corrosion of steel in reinforced concrete structure and the problems of large deflection and excessive cracks of FRP reinforced concrete structure.This paper introduces the reinforcement ratio of FRP-steel hybrid reinforced concrete beams under two failure modes,and presents the failure modes of FRP-steel hybrid reinforced concrete beams at different reinforcement ratio.
