The OConner fire-door flange is simply a design which givesthe flange at this point a much larger radius and largely increasesthe space around the fire-door ring or joint. The larger radiusacts in a manner similar to the corrugated fire-sheets by in-creasing the flexibility of the sheet and preventing the concen-tration of the stresses at the joint or sharp flange. The reversalof stresses at this point is particularly severe, due to the rapidcooling of the sheets whenever the door is opened. The in-creased water space around the door largely prevents the conce- ;<-%,.
