Observational and Forensic Insights for Wind Resilient Cities: Understanding the Effects of Extreme Winds on the Urban Built Environment

Extreme wind events, including typhoons, downbursts, and tornadoes, rank among the most economically devastating natural hazards globally. Yet systematic observational and forensic data on how these events impact urban built environments remain scarce, leaving critical gaps in our understanding of real-world structural performance under severe wind conditions.

Following a complete logical chain from wind field characteristics to structural responses and resulting damage, this talk presents a cohesive set of empirical findings covering typhoon-excited dynamic responses in super-tall buildings, as well as damage patterns induced by downburst and tornadoes in built environment. The talk also addresses often-overlooked wind-related hazards such as wind-driven hail, and introduces cutting-edge technical tools including UAV imagery for high-precision damage assessment.

By integrating in-situ full-scale measurement with post-disaster forensic analysis, this talk delivers practical, evidence-based insights into extreme wind impacts on cities. These findings directly support advances in wind-resistant design practices and help build stronger wind resilience in urban built environments.
