Well if an aluminum aircraft wing cut through the steel exoskeleton of a building, why wouldn't a steel girder do the same to a thin (relatively) steel box or hull?
If this is a serious post, velocity. If the girders of the bridge collapsed downward at 500 mph then yes, I’d expect them to have more of a “cut” but they certainly didn’t collapse at anywhere near such a speed.
Crumple zones?
It didn't cut the steel containers either...
Why would it cut them?
