Popis: Windstorms can cause significant damage to non-engineered structure and infrastructure due to the lack of consideration of wind force in design and construction. Historical windstorm events reflect that the windstorm damage is different than most of the other dynamic forces such as earthquakes, floods, tsunamis, and landslides. Bhutan frequently observes major windstorm events that cause significant damage to structures and infrastructures. Between April 2008 and May 2021, 51 windstorm events were recorded in Bhutan. Owing to widespread damages and losses in structures and infrastructures, it is imperative to depict the windstorm vulnerability of structures and infrastructures that would be instrumental, especially in a country such as Bhutan where windstorms are frequent and enormous losses are attributed to damage to structures and infrastructures. Based on historical windstorm observations and database, we present forensic interpretations of damage mechanisms and windstorm vulnerability analysis. Apart from this, we also present some strengthening techniques considering inherent vulnerabilities, especially for vernacular constructions in rural Bhutan.
