![]() ![]() A parametric analysis of corroded steel girder bridges was considered. The emphasis was focused on the parametric analyses of corroded steel girder bridges under two alternatives: (a) when steel bridge girder washing is performed according to a particular frequency, and (b) when no bridge washing is performed to the girders. The reduction of structural capacity was observed for both alternatives along the structure service life, estimated at 100 years. Measurement-based evaluation of noncomposite steel girder bridges.ĭOT National Transportation Integrated Search An economic analysis, using the Life-Cycle Cost Analysis method, demonstrated that it is more cost-effective to perform steel girder washing as a scheduled maintenance activity in contrast to the no washing alternative. The results from an experimental study into the behavior of noncomposite slab-on- steel girder bridges are presented. Two bridge : units were tested under increasing static loads beyond first yield of the girders with a flatbed trailer loaded with con. Top-lateral bracing systems for trapezoidal steel box- girder bridges. ![]() Trapezoidal steel box girders are becoming increasingly popular as a bridge system due to their torsional efficiency and aesthetic appearance. These bridge systems utilize one or more trapezoidal steel girders with a cast-in-place composite concrete. Strengthening steel bridge girders using CFRP.
