| Research Abstract |
In general, the FRP (Fiber Reinforced Plastic) bridges have high material cost and low rigidity against the deflection limitation of structural design. In this study, the increasing bending stiffness of FRP girders by bonding CFRP strips and bonding girder sections were proposed. The efficient flooring systems were developed and their validities were confirmed experimentally. Moreover, to demonstrate the practical use, the trial designs of footbridge over railway were performed.
