Abstract:ODOT Research Unit, in collaboration with Oregon State University (OSU), are continuing to study fiber-reinforced polymer (FRP) materials as a cost-effective, structurally sound methodology for upgrading bridges. The decision to use this approach was based on the early findings from this research effort. The Bridge Section and Research Unit contracted with OSU to build four full-size beams as nearly identical to the bridge’s originals as possible. One beam would be used for control. The other three would be strengthened for shear, flexure and shear plus flexure respectively. Since the Horsetail Falls Bridge is an historic structure, a special cosmetic coat was placed over the FRP composite and sensors to match the appearance of the original concrete.
