A pultruted hybrid composite girder is being developed consisting of carbon and glass fibers. The innovative feature is the optimum use of CFRP and GFRP in the flanges to maximize structural performance while reducing the overall cost by using glass fibers in the web section. In this paper, the cable-stayed bridges were trially designed using the developed hybrid composite girders. In order to utilize the lightweight of FRP, the construction site was selected to the free passage over the busy railway as a case study. The cable-stayed bridges were two continuous-span bridges with the span lengths of 5.5 m and 24.0 m. As a result, the feasibility of the proposed structures and the reduction of total cost were confirmed.
