Course Catalogue.

After participating in this course, you will be able to:

• Achieve economy on your projects by the skills developed through participating in the two workshops on designing and detailing connections under instructor guidance
• Design bolted and welded connections under static and dynamic loading
• Apply methods learned from the course to achieve economy in the design, fabrication and erection of steel structures

Description
This training course aims to provide participants with the methodology for designing, detailing, and specifying steel connections, along with connection installation procedures and inspections.

This training course was developed to serve as a comprehensive reference source for the design of steel connections for buildings and bridges. The theory and design criteria of bolted and welded connections are explained and cross-referenced to Canadian design code CSA-S16:19 – Design of Steel Structures and CSA-S6:19 – Highway Bridge Design Code. Emphasis was given to providing examples from actual practice.

The training course will include numerous design examples of different connection types. 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 training course.

Who Should Attend
Structural Designers • Consulting Engineers • Detailers • Specification Writers • Civil Engineers in large industries • Technicians and Technologists • Fabricators and Erectors of Steel Structures

Books to Accompany the Training Course:

CISC. Handbook of Steel Construction – Latest Edition. Canadian Institute of Steel Construction, Toronto, Canada.
