Function
A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.
residential / hotel / office
Structural Material
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.
Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.
Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.
Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.
Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

About Gate to the East
Topping out at just above 300 meters by way of its twin spires, Gate to the East was the first supertall to be constructed in the city of Suzhou. The building is located on the eastern side of the city and adjacent to Lake Jinji, with the design serving as a focal point for a new central business district as well as a gateway looking towards the historic city center. The archway draws from cultural influences of the Gardens of Suzhou, dating to the 11th-19th century and listed as UNESCO World Heritage Sites.
The archway also functionally splits the building with residential use on one side and commercial offices, hotel and a museum on the other. The two towers are then structurally joined at the top, the uppermost floor of which contains an indoor atrium landscaped with a Suzhou style garden. Both towers were framed with composite structures featuring a reinforced concrete core and a perimeter of large steel columns. Directly above the 7 story podium base, the columns flanking the void begin tapering inward towards the center. A large belt truss wraps the perimeter of the entire structure where the two legs join near the top.
The unusual shape of the tower led to a number of criticisms likening the structure’s form to a “pair of trousers” as well as nicknames such as “Pants to the East” applied to it even before the tower was topped out. The building as such had become well known to the rest of the world upon completion for this very reason and has in a way fulfilled an unintended role of serving as a gateway to Suzhou. Locally, the building has indeed become a focal point for the city as well as the business district that has since grown up around it, including the construction of the Suzhou Zhongnan Center. A major rail station below the archway ensures Gate to the East will continue to be a gateway for the emerging new economic heart of the city.
