FRP composites bridge deck has advantages of structural characteristics and rapid construction in the replacements of the deteriorated bridge deck. Although FRP composites have many advantages, the application in the bridge design has been retarded so far due to the lack of design guidelines. In this paper, the design example for the FRP decked concrete composite girder bridges is presented to verify the proposed design method. The design of connection in the design example is the flexible hybrid shear connection included steel reinforcements and FRP tubes. Finally, this paper may be design guideline for FRP decked concrete composite girder bridges required the composite action.
