Course Catalogue.

By the end of this course, you will be able to:

• Interpret and apply the National Building Code of Canada (NBCC) wind provisions to the design of low-, medium-, and high‑rise buildings
• Evaluate wind loads on structural systems, cladding, and building components using analytical, experimental, and computational methods
• Assess when code‑based approaches are sufficient and when wind tunnel or advanced studies are required
• Analyze building aerodynamic behaviour and wind‑induced responses to inform safe, efficient design decisions
• Apply wind engineering principles to real‑world design scenarios involving buildings, pedestrian winds, and environmental effects

Description

Engineers are routinely required to design buildings that must safely withstand complex wind actions while meeting code, performance, and constructability requirements. Wind effects influence not only structural framing, but also cladding systems, pedestrian comfort, roof performance, and long‑term serviceability, often under conditions of uncertainty and site‑specific variability.

This course provides a practical, engineering‑focused introduction to wind effects on buildings, grounded in the requirements of the National Building Code of Canada. You will gain a clear understanding of how wind loads are developed, how buildings respond to wind, and how code provisions are applied, interpreted, and supplemented when necessary. Through case studies and guided design examples, you will examine the strengths and limitations of code‑based methods, wind tunnel testing, and alternative analytical approaches.

Participants will leave with a stronger ability to evaluate wind‑related design challenges, justify engineering decisions, and apply wind engineering principles directly to professional practice across a range of building types and site conditions.
