That's a good outcome for a building really in danger of coming down.
Yeah that is great news. That would've been a complete shame.
I bet they got it for a ridiculously bargain price though. It almost seemed like you couldn't pay someone to take it. I can't imagine the complexity and frustration with the insurance claims of businesses in there and the property owners.
I always wondered what would happen if a tornado hit a downtown building or skyscraper. Now we know! While the first thing is ripping off siding and breaking windows, it sounds like the torsional stress on structural members is the worst of it. It sounds like if it were much worse, it would've torsionally bent and (with enough force) ripped beams/joints, at sharp vertical angles, almost as if you were to "twist" the top of it off until parts of it broke. Then with a much weaker frame with critical damage, further damage including collapse is possible. It is hard to imagine how that would look on such a large and tall building.
As far as I can tell, if this building would've been demolished, it would've been the largest building destroyed by a tornado (previously, the tallest building hit by one was a 35 story building in Ft Worth, but it had no structural damage).
