- Analytical study on shear capacity of steel I-girders with local corrosion nearby girder ends
抄録
Corrosion damage has been developed in web plates of main I-girder ends at the supports in aging steel bridges. When the end of main girder is corroded, shear capacity might deteriorate. In this paper, remaining shear capacity of I-girders with different corrosion shapes nearby supports was analyzed by elasto-plastic finite analyses, where four kinds of corrosion shapes and three rates of thickness reduction were considered. The results demonstrated the decrease of shear capacity depends on corrosion shapes and rates of thickness reduction. The most critical part of web plates of I-girder ends was discussed, along with the effects of local corrosion on shear capacity.
