Abstract: The breakage and fallout of glass facades may easily occur and significantly affect the enclosed fire dynamics. However, little is known about the effect of fire location on the glass thermal response. In particular, due to large size and various installation forms, glass facades perform differently when fire location alters. The different glass thermal performances, resulting from fire location changing from glass edge to center, are simulated using finite element method. Frame supported and point supported glass panes are employed. The glass stress distribution, breaking time, crack initiation and propagation are presented. It is established that fire location has a notable influence on thermal behavior of glass. Frame supported glass facades are more prone to breakage when fire located in the center of a pane. If the fire is positioned close to the fixing points, point supported glass facades will be more prone to breaking. For the purpose of comparison, relevant full-scale experimental results are presented. It is intended the results will provide useful knowledge for the fire resistance optimization of glass facades.
