Abstract

Tests were performed to obtain the flexural capacity of the innovative FRP-Concrete Composite Deck (FCCD) above girders. Test parameters were details of connection parts between FCCD and girder, such as continuity of FRP module, reinforcing ratio of FRP re-bars, and existence of shear connecting plate. As a test result, we found flexural strength of FCCD in the negative zone increases when FRP module is continuous, and reinforcement is increased, and shear connecting plate exists. And the flexural strength of all specimens give enough safety compared to the value needed in Korean highway bridge design code.
