摘要
纤维增强塑料(FRP)是一种新型的结构材料。它具有比强度高、耐腐蚀等特点,将其应用于桥梁结构中,具有传统材料难以比拟的一些优点。主要从混凝土桥梁预应力筋、桥面板、斜拉桥拉索及箱型梁四个方面,介绍了国外关于FRP在桥梁结构中的研究与应用,最后总结归纳了桥梁用FRP的性能特点以及对今后我国桥梁建设的启示。
Fiber Reinforced Plastics（FRP）is a new material for civil engineering, which has many advantages such as high strength-weight ratio and good performance in the corrosive environment, etc. It has some merits that traditional materials don＇t have when used in bridge structures. The paper mainly discusses the foreign research into and the application of FRP to bridge structures from four aspects-pre-stressed reinforcing bars of concrete bridges, ridge-deck, cable-stayed bridges and box beams, and it finally summarizes the characteristics of FRP used in bridge structures and the enlightenment it gives us.
