How do those skyscrapers that are built around a core work?

Question

Like the original world trade centre, what’s so special about building them this way and how does it keep all the weight up?

In: Engineering

Answer 1

How do they work in what sense? The core basically carries most of the weight of the floors which eliminates/reduces the need for walls elsewhere, that in turn opens up the space to match current open space requirements/enables you to have (almost) uninterrupted window walls etc. It’s not necessarily just cantilevered from the core, you might have a steel skeleton around it too/ but the weight is borne by the middle of the building, not the outer perimeter.
