Summary:In recent years, with the aging of bridges, many corrosion damages of steel bridges have been reported. In the case of replacing the splice plate against corrosion damage of the steel girder joint part, there is a method of installing an attaching additional member and replacing the corrosion damaged portion of the girder with a new member. However, there are cases where the space is narrow is difficult. In this study, FEM analysis considering the construction step was carried out for the replacement of the lower flange splice plate of the steel I girder, so even if there is less space under the girder. We propose effective installation position and cross section shape of the attached the additional steel plates.
