GRANVILLE BRIDGE

Location:

Vancouver, BC, Canada

Description:

537 m (1761 ft.) of steel truss eight lanes wide and 634 m (2080 ft.) of reinforced concrete viaduct.

Total length: 1171 m (3842 ft.)
Main span: 145 m (475 ft.)

Owner and Client:

City of Vancouver

Scope of Work:

Buckland & Taylor Ltd. designed the seismic retrofit with improvements that include:

• Reinforced concrete encasement and post tensioning that improved crosshead strength and ductility of several piers

• Cable restrainers prevent separation of pier and truss during a seismic event and bumpers reduce pounding between spans

• Bracing was strengthened, piers were made more ductile by adding concrete or steel jackets, or in some cases fibre-glass wrapping (believed to be the first use of this technique in Canada)

• Energy dissipating devices were added to the approach spans

  The work was phased (using a phasing policy developed by Buckland & Taylor Ltd.) in order to ease cash flow. Completed in 1996.
