The experienced team at the BLWTL delivers customized wind tunnel testing and analysis specifically for complex and specialty structures that defy conventional methods.
As the world’s first structural engineering wind tunnel, the BLWTL has a robust archive of wind engineering analyses of unique and complex structures. This enables us to confidently adapt and refine proven test programs for your unique project.
Our staff maintain diverse expertise in structural, mechanical and wind engineering, and are able to leverage our direct ties with other researchers at Western University. We are uniquely equipped to tackle complex and cutting-edge problems.
The BLWTL offers wind engineering testing and analyses of complex and specialty projects that defy conventional analysis and building codes. These structures – including spires, antennae, transmission towers, stadiums and other unique structures – require a methodology beyond standard, prescriptive engineering practices.
Leveraging our robust archive of research, we develop a customized wind tunnel testing and analysis program, ensuring that the structure’s unique geometry and its interaction with the wind environment is precisely modelled. The analysis ensures the complex structure is safe, stable, and compliant, mitigating the risks inherent in unique, cutting-edge projects.
Chimneys, Spires, and Antennae
Chimneys, spires, and antennae are slender, flexible structures which are often aerodynamically sensitive as a result of their cross-sectional shape.
Pressure model testing, force balance testing, dynamic section model testing and aeroelastic model testing in the wind tunnel can be used to evaluate wind loads as well as the vulnerability of these structures to aerodynamic excitation and the effectiveness of mitigation measures.

Large-Span Roofs and Canopies
Large-span roofs, such as those over stadiums, are structurally complex and can be susceptible to wind excitation.
Pressure model wind tunnel testing can provide local cladding pressures for the roof design and approximate the structural response. Aeroelastic model wind tunnel testing can directly simulate and measure the wind-induced response of the structure including loads and responses at key locations.

Solar Panels and Trackers
Wind tunnel testing for solar panels and trackers is a specialized form of structural analysis essential for determining extreme wind loads and dynamic responses of these lightweight, wind-sensitive systems.
Pressure model testing, dynamic section model testing, and aeroelastic model testing allow for the measurement of the wind-induced forces and responses to optimize the foundation and support structure and to recommend mitigation measures, where necessary.
Solar Panel Section Model
We deploy advanced instrumentation on operational structures to measure real wind-driven responses and provide real-time data on long-term performance and structural integrity.
We consult on the use of tuned damping systems for mitigating wind-induced motions. We have experience with damping systems in tall towers, chimneys, bridge cables, and more.
