Evaluation of the In-Service Performance of the Tom's Creek Bridge Fiber-Reinforced Polymer Superstructure;Final rept

摘要

The Tom's Creek Bridge is a small-scale demonstration project involving the use of fiber-reinforced polymer (FRP) composite girders as the main load carrying members. The project is intended to address two issues. First, by calculating bridge design parameters such as the dynamic load allowance, transverse wheel load distribution and deflections under service loading, the Tom's Creek Bridge will aid in modifying current AASHTO bridge design standards for use with FRP composite materials. Second, by evaluating the FRP girders after being exposed to controlled laboratory and service conditions, to begin to answer questions about the long-term performance of these advanced composite material beams when used in bridge design.
