would someone mind telling me why the roof of the Minnesota stadium collapsed? The thing was built in Minnesota, shouldn't the roof have been designed to take the weight of a lot of snow? For number of years the stadium has been there, has there never been a storm in Minnesota as bad as this one?
Gravity, baby!
Since it is an inflatable dome, it isn't going to take a lot of weight. The plus side is that it is easier to repair than a framed structure.
