Tall buildings are classified as follows:
Buildings taller than 200 meters, or more than 40 floors, are called tall buildings. Buildings taller than 300 meters are called Supertall (currently there are 78 very tall buildings in the world) and buildings taller than 600 meters are called Megatall. There are currently two very tall buildings in the world. One is the Burj Khalifa building in the UAE and the other is the Royal Clock Tower in Saudi Arabia.
The Council for Tall Buildings and Urban Habitats defines:
Tall building: a height of 200 m or around 40 stories
Supertall building: over 300 m; There are currently 78 supertall buildings around the world
Megatall: towers of more than 600 m. Only two buildings can claim this title, Burj Khalifa in the UAE and Makkah Royal Clock Tower in Saudi Arabia.

The TBI or Tall Buildings Initiative report has good recommendations regarding the design of tall buildings. According to this report, non-linear time history analysis with at least 11 earthquake maps should be used for the design of tall structures, and there is no longer any discussion of the coefficient of behavior in the design of these structures. Also, for these structures, the service level earthquake must be controlled, which of course can be used in a linear analysis. You can see some parts of this report in my high-rise buildings brochure with the link below.
