Abstract
For bridge structures using the traditional steel material, some problems are hard to solve, such as corrosion of steel bar and fatigue of steel deck. And the self-weight stress of the traditional high-strength steel as the material of cable stayed and suspension bridges will limit the main span and load-carrying. As a new type of high performance structural material, fiber reinforced plastic (FRP) has many advantages, such as small mass density, high tensile strength, excellent corrosion and fatigue resistant ability. Therefor in recent years, it has attracted much attention by the construction industry. In this paper, characteristics of FRP material are introduced and then applications of FRP material in bridge structures are discussed.
