The political-economy of water (and other diversions)
Yeah--awesome video, wonder who saw the problem emerging and thought to set up a camera to capture the collapse. Strange thing is, it's a DOME! Engineered to transfer forces laterally, withstand vertical pressure, all that stuff. The structural engineer needs a defense lawyer, and soon...
The Metrodome is an air supported structure. The inside air pressure is a smalll amount above the outside pressure. Because of this the roof does not behave like a traditional dome, transfering vertical pressures laterallly.That said, the snow event was well within building code limits. The dome also has a history of collapses, mostly in its early years.The roof fabric is nearing its projected life, and replacement of the roof was apparently normal scheduled maintenance costs.
