[Dead Corpse]

Depends on if it was literally designed to do that...

The design to collapse into its own footprint depends on the building being complete and intact, and that explosive charges are placed in specific places near the base.

Collapsing in an incomplete state, with fire-weakened structures over the entire height.... I wouldn't bet on anything. it could just as easily fall over like a felled tree, or crumble over many city blocks.

What an awful mess.
