How tall can a pure steel tower currently be built?

Theoretically, how tall can a pure steel-constructed tower be built today?

- The reason I ask is because I have noticed that the latest tallest buildings in the world are made using a steel/concert composition rather than a pure metal approach...

The tallest is Willis (Sears) Tower in Chicago (1974). Maybe it's the limit, because of the pendulum effect.

Even in steel framed towers, concrete is still used for the floor slabs. Concrete is poured on top of the metal decking of each floor.

I can only assume that many do... But it has nothing to do with integrity and stability of the structure... You can use wood, glass, plastic... Whatever you want really - it is supported by the building, not supporting it.

I'm not a huge fan of poured concrete (although Precast is fine) in buildings...
I associate it with cheap work and unskilled labor. I hate crooked things.
I like straight prefabricated materials that fit with an ultimate precision.
