Axial Shortening - Multi Storey building

[Seb_]

Hi All

in my professional life as an engineer, i have always worked with low storey structures, say max. 4 levels.

I have never been exposed to tall building, however i have always questioned myself how do engineer deal with the axial shortening of tall building.

As an engineer, what needs to be achieved?

thanks in advance!

I don't work with tall buildings myself, but in the 4-14 story range, we proportion the columns so that they have similar axial stress. Same with footings.
