摘要：
The 26.87-m, single-span Beaver Creek Bridge on U.S. Highway 6 in Utah was built in 2009. Elements of the bridge included AASHTO Type IV prestressed concrete girders and posttensioned, full-depth, precast concrete deck panels reinforced with glass fiber reinforced polymer (GFRP) bars. The bridge was given three static and five dynamic truck load-controlled tests before it was opened to traffic. Vertical acceleration data was also collected from random truck traffic. Dynamic truck load data was used to verify a finite element model and obtain dynamic load allowance (DLA) values. DLA was determined to be a function of the number of axles, axle group weight, and axle spacing. The maximum DLA for the bridge with a GFRP-reinforced concrete deck was found to be less than the value specified in the AASHTP LRFD Bridge Design Specifications.
