Description

Connections form a very important part of any steel structure and integrity of the structure depends on them. Accurate details and specifications are required for fabrication to ensure trouble-free erection. There is a potential for achieving economy in designing and specifying connections which is the focus of this workshop. Results of recent research on steel connection detailing and fabrication will be briefly introduced. The seminar will focus on connection design specifications as set forth in the CSA Structural Steel Design Standard, CAN/CSA-S16-09, and the Canadian Highway Bridge Design Code, CAN/CSA-S6-06. The seminar will include update of changes in S16-09 as compared to S16-01. Seminar notes will include numerous design examples prepared by the instructor for teaching purposes.

Additional Information

Objective To provide participants with the methodology for designing, detailing and specifying steel connections. Who Should Attend Structural designers, consulting engineers, detailers, specification writers, civil engineers in large industries, technicians and technologists, fabricators and erectors of steel structures. Bring With You Your own Handbook of Steel Construction-Latest Edition (2010) and the book: Hollow Structural Section: Connections and Trusses- A Design Guide, Latest edition by J.A. Packer and J.E. Henderson. You can obtain both books from the Canadian Institute of Steel Construction.
