Seismic Design of Steel Framed Buildings 2006

(May 2006)

Available with course registration only. See schedule.

These design notes are a reference supplement to the CISC continuing education course on “Seismic Design of Steel-Framed Buildings”. They contain the majority of the set of slides shown during the course presentations, together with additional background information on each slide. This publication is part of a continuing effort by CISC to provide practical information to assist building designers in the efficient and economical use of structural steel.

The notes illustrate the design of various types of seismic-force-resisting systems (SFRS) in different Canadian locations with varying seismicity. They refer extensively to the National Building Code of Canada 2005 (NBC 2005) and to CAN/CSA-S16-01 “Limit States Design of Steel Structures” including the S16S1-05 Supplement. In addition, there are many references to the CISC Handbook of Steel Construction, 9th Edition, 2006 and CISC publication “Moment Connections for Seismic Applications”.

The example structures range from 1 to 10 storeys and consist of concentrically and eccentrically braced frames as well as moment-resisting frames. The structural systems include seismic-force- resisting systems in Conventional Construction, Limited-Ductility, Moderately Ductile and Ductile categories.

These design notes focus on design calculations for load combinations involving seismic loads and effects only. Liquefaction is also beyond the scope of these notes. Load combinations that exclude seismic effects, such as those involving gravity loads only and those involving the effects of wind, have been excluded. It should be noted that these load combinations are essential in the design of building structures. Another CISC publication “Steel-Framed Commercial Building Design Notes” addresses these topics.

The 6 seismic force resisting system designs are as follows:

  • Limited-Ductility (Type LD) Concentrically Braced Frame – Chevron Bracing (4-Storey Building in Fredericton)
  • Moderately Ductile (Type MD) Concentrically Braced Frame – Split-X Bracing (6-Storey Building in Montreal)
  • Ductile (Type D) Eccentrically Braced Frame (10-Storey Building in Burnaby)
  • Limited-Ductility (Type LD) Moment-Resisting Frame (4-Storey Building in Montreal)
  • Ductile (Type D) Moment-Resisting Frame (4-Storey Building in Victoria)
  • Conventional Construction Braced Frame – Tension-only Bracing (Single-Storey Building in Toronto)
