Abstract

Abstract

On April 27， 2024， the Baiyun District of Guangzhou City was struck by a tornado， leading to severe damage to a large number of buildings， particularly light-gauge steel structures， including roof uplift， facade damage， and collapse. Based on the on-site investigation， the paper analyzed the damage characteristics and causes of roofs， purlins， and steel columns of light-gauge steel structures when confronted with tornadoes. The results indicated that excessive high wind loads were the primary cause of damage to light-gauge steel structures. Different building structural types exhibited distinct damage patterns. Light-gauge steel plants designed and constructed strictly in adherence to building codes primarily showed damage to their envelope systems while maintaining a relatively robust wind-resistant performance of the main structure， towering structures were prone to overall torsional deformation and support failure under the impact of tornadoes. The design and construction quality significantly influenced a building’s resilience against tornadoes. Appropriately decreasing the space of purlins and enhancing the bearing capacity of upright columns could effectively improve the capacity to withstand extreme wind hazards like tornadoes.
