ABSTRACT

Durability of bridges becomes increasingly important in order to reduce future maintenance costs. Considering these circumstances, the authors developed a Non-metal bridge that completely eliminates the use of steel members such as steel reinforcements and prestressing steel. Aramid FRP rods were used as prestressing tendons to provide tensile force reinforcement. To eliminate the need for shear reinforcement, we developed a high strength fiber reinforced concrete with high shear strength. That structure was conducted by wheel load running tests to verify the fatigue durability. After that, a half scale butterfly girder structure was built by using segmental method and tested to confirm that the structure was sufficiently durable.
