Abstract

Roof collapses of any nature have severe impacts on building owners in the form of financial losses, and on building occupants in the form of physical harm. It has been observed recently that lightweight steel roofs subjected to snow loads account for a large number of roof collapses every year in the United States. The combination of the impacts and potential risk associated with lightweight steel roofs makes it important to properly understand their behavior under snow loads. This study focuses on a specific type of lightweight steel roof: open web steel joist supported roofs. Open web steel joist roofs with different design characteristics are analyzed in order to form a better understanding of how these types of roofs behave under uniform and drifted snow loads as well as their associated risks.
