Griffiths Drive Pedestrian Bridge, Burnaby, KWH Constructors
Starting on the West Coast, we return to the Vancouver Convention Centre Expansion to reveal the complex engineering behind this structure with this third article by Robert D. Simpson and Jacques Beaudreault. It is one of several recent steel projects constructed in BC with some especially constructed for next year’s Winter Olympics. The 2008 BC Steel Design Awards, Engineering Award recipient is the state-of-art Olympic Park ski jumps. The image above is of the Griffiths Drive Pedestrian Bridge in Burnaby, which received the BC Region’s Architectural Award. Moving east, we have numerous exciting structures featured in the 2008 Quebec Region’s Steel Design Awards.
John Leckie concludes our three part series on Residential Construction with a review of applicable composite steel floor systems, including the Hambro system. “Seismic Corner” examines limited-ductility moment-resisting frames – connection options. “Ask Dr. Sylvie” answers questions on elliptical tubes, K factors for X-braces, different values used for notional loads in various standards and, pays tribute to Canadian structural steel researchers and the Steel Structures Education Foundation. Will Koroluk returns with “For Green’s Sake” discussing the fundamental efficiency of steel.
