A recent study from Florida International University highlights that skyscrapers, constructed to endure strong hurricanes, performed poorly against less intense but chaotic windstorms called derechos. Analyzed after severe damage in Houston during a derecho in May 2024, researchers found buildings designed for high hurricane winds suffered notable facade damage due to unpredictable downbursts that reached 90mph. This contrasts with their durability during Hurricane Beryl when sustained winds were similar. The study suggests significant implications for urban planning as climate-related severe weather becomes more frequent.
The findings raise concerns about the resilience of tall buildings, suggesting that they may not be as prepared for derechos as for major hurricanes.
The damage in Houston reveals how downburst winds from derechos can create complex pressures on skyscrapers, leading to severe facade damage even at lower wind speeds.
