Abstract:Twelve reinforced concrete deck panels were tested to study the potential of glass fiber reinforced polymer (GFRP) rebars as a replacement for epoxy coated steel (ECS) rebars in concrete bridge decks. Span lengths during testing were 2130 mm and 2740 mm. Three reinforcing schemes were evaluated in the study: an ECS reinforcing scheme, a GFRP reinforcing scheme, and a Hybrid reinforcing scheme with a top reinforcing mat of GFRP rebars and a bottom reinforcing mat of ECS rebars. A shear diagonal tension, failure mode was observed in the testing of the deck panel specimens with GFRP tensile reinforcement. Based on the test results, two equations for predicting shear capacity of GFRP reinforced concrete sections are presented.
