The six-lane President Costa e Silva Bridge between Rio de Janeiro and Niteroi over Guanabara Bay in Brazil spans the main shipping channel with two parallel three-span continuous steel box girders 848 m (2782 ft) long. The box girders are jointed by an orthotropic steel deck with asphalt surfacing. A thorough field study was conducted of the steel box girders under erection and service load conditions. As part of this investigation, the service life behavior of the orthotropic steel deck was examined. Field studies were carried out on a portion of the orthotropic deck to determine the stress history under a random traffic sample so that the fatigue susceptbility of the welded details could be assessed. The investigation revealed that the orthotropic deck will provide satisfactory service throughout its life. Indications are that certain splices of the trapezoidal deck stiffeners may have the potential for fatigue crack gorwth. Periodic inspection of these splices will provide ample safeguards and ensure that their capacity is not impaired. /Author/
