Floors
Above Ground

The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

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.

Structural Material
Steel
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.

Steel and the Skyscraper City: A Study on the Influence of Steel on the Design of Tall Buildings

Shelley Finnigan, ArcelorMittal; Barry Charnish, Entuitive; Robert Chmielowski, Magnusson Klemencic Associates

At the turn of the century, building design began to evolve. Improvements included indoor plumbing, the advent of escalators, and creation of the “Chicago window.”...

About 150 North Riverside

The 150 North Riverside site is located prominently at the confluence of the three branches of the Chicago River and less than one block away from one of Chicago's busiest commuter train stations. With exposed railroad tracks on the west side of the site and the city requirement for a public right-of-way on the east side, the remaining area on which to build was considered impossibly narrow, and the site sat undeveloped for decades.

Utilizing a unique core-supported structure with a very small footprint at grade, the design resolves the site challenges and provides a Class A office tower with efficient, column-free floor plates. The building’s unusual core-supported design results in a 221-meter tower resting atop a base that is merely 12 meters wide. The building is most noticeably significant for the narrow aspect ratio of its core; at 20:1 it is among the world’s thinnest. In consideration of this, the building also contains the first-ever application of a 12-tank tuned liquid mass damper (TLMD) at the tower’s top to manage both building drift and acceleration. With a total of 605,665 liters of water, the TLMD also provides city-approved fire protection storage tanks to supply the building’s sprinkler system, a creative dual purpose that is a Chicago first. The 16 sloping columns at the cantilevers feature the largest rolled-steel shapes ever used in a high-rise building in the U.S. The shapes are 1,092 millimeters deep and weigh 1,377 kilograms per meter.

This narrow building footprint accomplishes several strategic goals, in addition to facilitating column-free office space. It also creates a dramatic interior space in the lobby, while allowing for more than 75 percent of the property to be unenclosed outdoor space. The tower’s limited footprint and the angled sweep of its underside appear to usher the river past the site, breaking down the tower’s considerable mass and presenting a balanced composition.

Tenants and visitors enter through a dramatic, 27-meter-high lobby enclosed by a glass-fin wall hung from the structure above. The lobby features the “150 Media Stream,” a one-of-a-kind curated multimedia wall that showcases the work of local and other digital artists. The 46-meter-long, site-specific installation provides a lobby focal point while also addressing the transition between the opaque wall over the parking deck and the glass-fin wall above, using 89 LED blades, carefully choreographed in varying lengths and widths.

Building amenity spaces include a restaurant, bar, fitness center and conference center – all with water views. The condensed lobby and elevator cores open the majority of the 8,093-square-meter site as a landscaped public park, plaza and riverfront promenade.

Outside, the park and plaza provide more than 300 linear meters of seating, multiple assembly/event spaces and 110 meters of at-grade Riverwalk frontage, which has already become one of the most populated walkways for downtown commuters. Those who negotiate the grade change of the landscaped plaza on the west side of the tower find themselves in the unique position of being outdoors and at eye level with Chicago’s famous elevated train, without being in a station.
The structural acrobatics performance has paid off commercially as well as urbanistically, taking what was once deemed an unbuildable site and creating an optimal mix of leasable floor space, public outdoor space, and semi-public indoor space, complemented by custom-designed artwork.
