How many wrong turns do you take before consulting the road map? Well if you are like me, one too many. For designers faced with so many changes in Part 4 of the 2005 NBCC, CISC has developed a “road map” to assist designers of steel buildings in selecting the appropriate seismic force lateral-load resisting system. Alfred Wong explains the various terms and helps guide you to the most cost effective braced frame configuration.
In many cases, “fly-over” bridges have been built in concrete. The reasons for the use of steel for Structure 1.1 are convincingly laid out in John Leckie’s article on the Anthony Henday “fly-over” bridge, recently completed as a 3P venture in Edmonton.
Canadians hold a commanding lead in the production and use of hollow structural sections (HSS), a lead first cultivated by Stelco more than 30 years ago. Thus, it was with pride that Canada hosted the 11th International Symposium on Tubular Structures last year in Quebec City. Dr. Sylvie played a significant part in helping host the event and, with Dr. Packer and Silke Willibald, reports on how, “In Canada, Tubes R Us”.
How can you achieve a 30% energy saving over the Model National Energy Code? Merge pre-cast concrete floors, “breathable” steel wall cladding, with structural steel framing, as in the new GTAA’s Fire and Emergency Services Training Institute. Receive not only a project energy savings of 30%, but achieve a Silver LEED rating as well! Michelle Ponto explains in detail on page 12.
Toronto Star’s urban affairs and architectural columnist, Christopher Hume, states, “we now inhabit the Age of Steel”. How so? Well, we will let him explain that to you on page 22.
