I'm sure it's a cool building, but...

A core is not a genuine structural element-- it HAS Structural elements, an=

In most tall buildings, the core is specifically to "hold up the building".

OK, that's contrary to my understanding, so thanks--- How does it do so?

I had recalled reading that somewhere, but after doing some research,
it appears that the exterior diagonalized tube is is the structural
system in most common use for tall buildings.

What I had earlier read was that some buildings have a concrete
structural core, and the floors are cantilevered from the core.
