Cover Story: Soil–steel composite bridges have become increasingly popular for short-span bridges. The load carrying capacity and integrity of such structures highly depends on the condition and capacity of the steel arch element. A major drawback, however, is the corrosion and subsequent loss of cross-sectional capacity. Fiber-reinforced polymer (FRP) composites offer an attractive alternative to replace the steel in these types of bridges. FRP composites have significantly improved durability characteristics compared to steel, which will reduce maintenance costs and improve life-cycle costs. This paper presents a new concept of using FRP to construct soil–FRP composite bridges. Various aspects of design and manufacturing are presented along with results and conclusions from a case study involving alternative bridge designs in steel and FRP composites. View this paper.
