    Numerical Assessment of CFRP Retrofit Effect for Repairing Corroded Steel Girder Ends by Local Stress and Displacement Distribution
    Author(s): Rusandi Noor* and Hiroshi Tamura

    Background: Post-retrofit inspection of steel bridges can be particularly challenging due to the lack of visual accessibility by the inspector. This study numerically investigated the repair and reinforcement behavior using CFRP (Carbon Fiber Reinforced Plastic) for corroded steel girder ends, consisting of 3 configurations bracing a simple span steel bridge. Stress transformation studies are conducted so that the steel girder ends stresses due to various types of loading can be predicted. The CFRP retrofit model was validated to evaluate the representation of CFRP in the existing system. The validated corroded girder model showed high-stress values under the design loads. The result has been studied based on a computational model to gain the shape of the stress distribution of CFRP to capture the response in different loading types. The contribution of the 50 mm curv.. Read More»
