| 摘要： | The Boeing North Bridge is a multispan girder bridge spanning the Cedar River in Renton, Wash. All aircraft assembled in Boeing's factory are towed over the bridge to Renton Municipal Airport, where they undergo final inspection before takeoff. The design and construction schedule for the bridge was accelerated to accommodate Boeing's increased production. To meet the constraints imposed by environmental regulations, winter construction, airport operations, and the surrounding community, the new bridge was designed using precast concrete columns, partially precast concrete crossbeams, and full-depth precast concrete deck panels. Due to the high seismicity of the site, the connections between the substructure elements had to be seismic resisting. This paper summarizes the details of the precast concrete bridge elements and the construction methods used. |
