| description abstract | This study examines 1,029 snow-induced building failure incidents in the United States between 1989 and 2009 and 91 international incidents between 1979 and 2009. Incidents were identified through newspaper archives, including 1,345 articles from 883 unique sources. Most U.S. incidents occurred in New York, New Hampshire, and Massachusetts. Findings show that 37% of all buildings experiencing snow-induced failure incidents in the United States were of metal/steel construction and another 37% were of timber, while 53% of international incidents were metal/steel and 17% were concrete. Warehouses, factories, and commercial buildings were the most common buildings affected. Failures were attributed to the amount of snow, rain-on-snow mixes, and building problems. Monetary impacts included building damages ranging between $1,000 and $200 million and business interruption associated with an average building closure of four months. Nineteen fatalities and 146 injuries were reported for the United States, while 293 fatalities and 586 injuries were reported internationally. These findings describe building failure trends, which may be significant, considering potential impacts of accelerating global climate change on the patterns of snowfall frequency and density. | |
