Sorry Michael, no specific experience, but I do know that DIA (Denver international Airport) has a large fabric structure that is un-protected. They put sprinklers is all of the subdivided vendor spaces under the roof, but nothing at the fabric roof itself. Which basically leaves the main hall un-protected except with some HSW's spaced around the grand hall 300 x 1200 at the mezz. height.

The manufacturers data says it will fail at 250 degrees celcius which is well above the 68 degree activation temperature of the sprinkler however if the fire is in between sprinklers the centreline temperature of the fire plume rises above 250 degrees C very quickly. Does anyone have any anecdotal experiences of fires in these types of structures with spirinklers installed?
