Response of No-Name Creek FRP Bridge to Static Loads, Moving Traffic Loads and Impact Traffic Loads
No-Name Bridge is the first all composite road bridge in the United States. It was built by Kansas Structural Composites Inc. in Russell, Kansas in 1996. The bridge is located on a county road three miles east of Russell, Kansas. On September 18, 2004, field tests were conducted to examine the response of No-Name Creek Composite Bridge to static loads, moving traffic loads, and impact traffic loads. An AASHTO (American Association of State Highway and Transportation Officials) type 3 truck was used to apply load to the bridge. The gross weight of the truck was 70,340 lb. Four kinds of loads were applied during the tests: 1. Static load tests: the truck rested on the middle span location of the bridge; 2. Creep load tests: the truck moved through the bridge as slow as possible; 3. Dynamic traffic load tests: the truck moved through the bridge at controlled speeds, and; 4. Impact load tests: the truck moved over an obstacle at controlled speeds. When the truck passed over the obstacle, an impact load was applied to the bridge. In all these tests, laser sensors were employed to measure mid-span and quarter-span deflections. Previously, two static field tests had been conducted on Nov. 19, 1996 and May 18, 1997, respectively. These results are compared with current results. In addition, dynamic responses of the bridge to dynamic traffic loads were measured, so are discussed in this report.
