Summary
The Truckee River Bridge is designed as a single span bridge simply supported on cellular abutments that is proposed to carry California State Route 89 over the Truckee River in the city of Tahoe City, CA. The cellular abutments allow bike paths to pass below the structure at each side of the river. This bridge is part of a larger realignment project led by Central Federal Lands and funded by the Federal Lands Access Program.
During initial design, the proposed structure was detailed with three spans, a curved deck, and deep foundations. By reducing the spans to a single span supported on cellular cast-in-place abutments on spread footings, the project cost was greatly reduced. To design the columns that formed the river side of the abutment, the structure was modeled in Midas Civil 3D to evaluate the plastic response of the columns under severe seismic loading. The inelastic analysis in Midas was done using the General Section Designer as well as the Pushover Analysis function within the Midas Civil 3D program. A similar analysis was done using more conventional methods and results were compared.
