Description

Description This prefabricated bridge system includes combinations of superstructure elements and decks fabricated together before transporting them to the job-site. This system is good for the rapid time of construction it provides; this is due to the bolt connections on-site and the lack of field welding. Some have the negative perception that these bridges are only useful for temporary bridges or that the span must be right for the prefabricated sections available. Pretopped girder sections can be designed to be permanently installed and are specifically designed for the required span. Different groups have developed different methods of pretopped girder bridges. Application Pretopped girder sections as sections of preconstructed steel framework with bridge decking already installed can be used on the bridge as both the superstructure and bridge deck. Constructability All bridge welds are performed during fabrication and not at the bridge site. Bolted connections are used on site in order to connect the bridge segments during installation. These bolted connections allow for easy and quick construction with small crews and light equipment.
