We had a test of this when a tornado hit Czechia some time ago. I think only the smaller commie blocks remained structurally sound.

  For those of us who are unfamiliar with the building materials and styles of the area, what was different about those blocks that made them more structurally sound?

    They're built out of large slabs of concrete with steel beams in between and have flat roofs - that's about it. Terrible to live in, but neither a car at speed nor a falling tree can punch a hole in them. Also they weren't built as close to each other as modern buildings are, so debris from one mostly don't reach the other.

    The square-cubed law. They're all reinforced concrete, but for the same wall thickness a smaller building will be stronger.
