I never knew that. That's kinda scary actually.
I know from when they built it that the north upper deck sits on a bunch of bigass caissons. The ground under the stadium is pretty heavily run through with caves and voids. They unearthed a substantial sinkhole when they converted the field to grass.
Let's assume the jumbotron is between 200 and 300 feet tall. For a 105 mph wind design, the velocity pressure at that height for that structure is in the neighborhood of 34 psf. The surface area of the jumbotron is 4,500 Sq. Ft. Comes out to a net lateral force of 153 kips (153,000 lbs). Per column, that translates to an overturning moment of 19,125 kip*ft (assuming the point of loading is 250 ft above the base of the columns). To come up with a footing/caison layout big enough to resist that moment, you would certainly have to compromise the foundations of historic buildings in the area and would probably just be forced to demolish them. The point is, you can't just sneak a jumbotron in without some major ramifications to the stability of existing structures.
After they're done rotting behind UT Hospital, that's where Dr Bass stores them.

I never heard this before about seeing The Hill.
Thanks for the info. :hi:
