Wind-Related Issues in the Design of Tall Buildings

Date: January 31, 2017

Presenter: Jon Barratt, P.Eng., Project Manager, RWDI

This was a stimulating evening discussion of wind-related risks, prescriptive wind loading based on the 2012 BC Building Code, and the methodology and benefits of alternative modelling and analytical approaches for the derivation of wind loads – specifically wind tunnel testing.  Changes to wind and snow load provisions in the 2015 NBCC will be discussed, including some thoughts regarding how these changes are anticipated to impact projects in the Lower Mainland.

Tall buildings are becoming more commonplace in many cities in our region.  As such, the need to consider wind-related impacts is critically important in the development of structural and cladding loads and when evaluating occupant comfort at upper floors.  Through our experience with thousands of buildings located around the world, including several in the Lower Mainland, RWDI has helped project teams understand the role that wind will play in the design of high-rise buildings, bridges, stadia, airports, art installations, and other unique structures.  Examples of projects, both local and international, that have faced issues related to wind were be presented to illustrate some benefits of wind control mitigation.
