Title: Regional System Selection

The Todd Hill/Desi Kiss thread has brought up an intersesting sidebar:

Regional Structural System selections.

How and why are various area of the country (world) approaching some of the following building types.
I know some of this is obvious, but entertain us anyway.

Low rise:
Multiple floor:

Here in our area:
low rise: is open web joists on steel beams with load bearing masonry walls or braced TS column frames.  Metal deck or poured gypsum roof diaphragm.

multiple floor: moment (sometimes braced) frames with composite beam floor assembly (sometimes open web joist and conform deck) with metal deck roof diapragms.  very little concrete structures.  cost is usually the determinant (as well as speed of erection, but then again, that's cost isn't it ?)
