Here's the engineer's perspective on this:
- Concrete can tolerate high compressive loading.
- Steel can tolerate high tensile loading.
- Steel + Concrete = best of both worlds.
I'm sure some architect or engineer figured out the best way to optimize space/time/cost through the right combination of steel and concrete. BTW, thanks for answering my original question.
