Increases and Reductions in Wind Loads due to Aerodynamic Interference

Presenter: Dr. Tom Mara (The Boundary Layer Wind Tunnel Laboratory)

Date: November 21, 2017


Local effects due to adjacent structures can significantly impact the wind loading experienced by a structure in a developed environment. Aerodynamic interference phenomena such as buffeting, channeling, and sheltering can have unique, and occasionally unpredictable, effects on the loading and response of tall buildings. While sheltering is often beneficial, wake buffeting and channeling may result in increased responses for some wind directions. Certain configurations of adjacent buildings can lead to acute interference effects, and have been identified through a substantial wind tunnel test program at the BLWTL. This presentation will review the relevant underlying mechanisms driving aerodynamic interference and progress to the illustration of both beneficial and detrimental situations which may arise. A discussion of how interference effects are treated in national standards and local building codes is also provided.

Speaker Bio:

Dr. Tom Mara is a Research Engineer at the Boundary Layer Wind Tunnel Laboratory and an Adjunct Research Professor in the Department of Civil and Environmental Engineering at Western. He has over 10 years of experience in wind tunnel testing of tall buildings, long span bridges, and other wind-sensitive structures.
