I don’t know much about high-rise building construction, but my instinct tells me that there’s no way anyone makes concrete support columns all the way up like that, Just because of how tall the forms would have to be without a building being there yet. There is likely steel behind all of that
You would have a form per floor. Fill, and set concrete lift up form for next floor. Repeat.
I’m sure you’re right, but it just seems like it wouldn’t be as strong that way, Unless it was continuous all the way up. I know at least with steel they bolt the beams together so that it runs from the ground foundation all the way to the top. I’m sure there’s ways they can bolt big concrete pillars together though. I’m just talking out my ass here, I really don’t know about anything other than residential construction
There is steel (has to be) but they do 1 floor at a time. They can go very high this way. Worked in the trades for a few years on commercial construction.
Chinese steel. Nuff said.
