Modern building codes provide a solid foundation for wind design, but they rely on simplified assumptions that cannot fully represent the aerodynamic behavior of today’s tall, slender, and architecturally complex structures. As buildings push the limits of height and form, engineers are increasingly required to make design decisions beyond what prescriptive code provisions can reliably or economically address.

This course is developed for practicing structural engineers who need to bridge the gap between code-based wind design and real structural performance. It focuses on advanced wind tunnel testing and, more importantly, on how test results are interpreted and directly integrated into structural analysis, façade design, and serviceability evaluation. Through practical, experience-driven explanations, the course reveals critical behaviors—such as torsional response, cross-wind excitation, localized façade pressures, and occupant comfort limits—that are often underestimated or completely missed by code-based methods. These insights enable engineers to deliver safer, more efficient, and performance-driven designs while avoiding unnecessary conservatism and costly redesigns.

This is not an overview course and not a collection of disconnected lectures. It is a comprehensive, structured program that walks you through the full wind-engineering decision chain used in real projects.

By taking this course, you will:

• Build a complete mental model of wind–structure interaction, starting from atmospheric flow and aerodynamic loading through structural response, serviceability, and façade performance.
• Work through the full lifecycle of wind tunnel–based design, including test planning, model scaling, data quality checks, interpretation of results, and direct integration into structural analysis models.
• Study wind effects that are rarely treated in depth—torsional response, cross-wind excitation, directional sensitivity, localized peak pressures, and human comfort criteria.
• Analyze multi-disciplinary interfaces between structural systems, cladding design, vibration control, and occupant perception.
• Engage with real project case histories that connect theory, testing, analysis, and final design decisions.
• Explore advanced and emerging topics such as CFD screening, reduced-order models, digital monitoring, and digital twins within a unified framework.

In short, this course is intentionally dense, rigorous, and practice-driven. It is designed for engineers who want depth—not shortcuts—and who value a course where each module builds on the previous one to form a complete, defensible methodology.

Because practical guidance on wind tunnel–driven design is rarely available outside specialized consulting practice, this course offers a unique opportunity to gain knowledge typically acquired only through years of real project experience—providing a clear framework for confident decision-making when code assumptions are no longer sufficient.
