Intesa Sanpaolo Tower is under construction in Turin,itlay and it will serve as headquaters for Intesa Sanpaolo bank. It is designed by world-famous architect Renzo Piano. It will have 37 floors + 6 basements on its completion and has a footprint of 1000 square meters. Reason for mentioning it here is the load path used in this building. Only, Six mega columns will transfer entire gravity load of building. Most of the floor load of entire building is transferred to these columns through trusses (only on of them is visible in attached photos) located at about 4 storeys above ground. Laters load are caterred for by steel cable bracing

Its the same system used in CMA Tower, Riyadh (my first project). You have mega columns for gravity loads. And sure this building must be having OUTRIGGERS....for lateral loads which attracts lateral forces from outer columns and structure to inner concrete core designed to resist lateral loads. The core walls of this tower at ground floor may be 1.8m thick with seismic time period around 5 seconds. These are my estimates. I know i am wrong most of times
