Houston Skyscrapers Vulnerable to Derechos, Study Reveals

A recent study from Florida International University reveals that skyscrapers designed to withstand hurricanes are significantly more vulnerable to derechos, a type of fast-moving windstorm. The research, focusing on the extensive damage caused by a derecho in Houston on May 16, 2024, found that downburst winds peaking at 90 mph rebounded off buildings, causing severe damage to facades. Despite these structures being engineered for 156 mph hurricane winds, they fared poorly against the sudden gusts and localized forces produced by the derecho. The findings underscore the need for reevaluation of building designs as climate change leads to more frequent and intense weather events. Researchers highlighted that the peculiar dynamics of downbursts could lead to even greater damage on lower floors of tall buildings than previously recognized. This study serves as a crucial reminder for urban planning and building resilience in cities globally facing similar risks.
