The lift core is primarily for building stability so that the building sway will be within the acceptable limit to give comfort to the building occupants.
Any tall building have to be designed to resist wind resistance and the core will be used to resist the wind load. Columns can also be used but the impact will not be as significant as the core.
During the design stage, wind tunnel simulation will be carried out to confirm the theoretical calculation is correct. Usually, the core will house all the services such as lifts, pipe risers etc as those services require precise sway tolerance to ensure smooth ride for the lifts.
During construction, the core is just like the heart of the building, and will be constructed first ahead of the floors and perimeter columns. This will allow tower cranes be installed within the core and supported by the core structure.
