CANADIAN SEISMIC DESIGN PROVISIONSFOR STEEL STRUCTURES

摘要

The CAN/CSA-S16 "Limit States Design of Steel Structures" Standard is used in Canada for the design of steelrnstructures. Clause 27 of CSA-S16 includes the earthquake design provisions for seismic force resisting systems forrnwhich a ductile seismic response is required. CSA-S16 was last published in 2001 and a supplement has beenrnprepared in 2004 to make the Standard consistent with the upcoming 2005 edition of the National Building Code ofrnCanada. This paper outlines the seismic design requirements of CSA-S16 and summarizes the changes incorporatedrninto the 2004 Supplement. Suggestions for possible future improvements are also discussed in the paper.
