Abstract:Since 1996, over 30 Fiber Reinforced Polymer (FRP) composite bridges have been installed in the United States. Bridge locations are in Kansas, Missouri, New York, Iowa, Colorado, West Virginia, Ohio, California, Idaho, Washington, Pennsylvania, Illinois, Maryland, Oregon, North Carolina and South Carolina.
Compared to traditional steel and concrete bridge structures, the FRP panel shows several significant advantages: reduced weight, higher strength, better corrosion resistance and quicker installation. However, FRP materials exhibit different physical properties. As such, a composite bridge would demonstrate different deformation and failure patterns than a traditional bridge. During the past years, much experimental research has been conducted to investigate FRP bridge deck performance. Most experiments divide into two types: 1) static and fatigue tests in the laboratory and 2) real traffic load tests in the field. These experimental results, as well as FEM analytical results, have served as baseline data for FRP bridge deck design.
