This paper dealt with the applicability of GFRP materials as reinforcements for a steel box girder bridge deck. The purpose of this study is to provide detailed design procedures with a code-based text for GFRP composites for civil engineering structures. From the example design, the deck was optimized from a serviceability perspective but was quite overdesigned with regard to flexural strength and creep rupture stress, due to its relatively low longitudinal modulus but high strength. We may conclude from these results that it is advisable to check the serviceability limits before optimizing the design for strength or starting the design from the serviceability calculation.
