Canton Tower
Guangzhou China
Height

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

To Tip:

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).

Floors

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.

About Canton Tower

Located on the banks of the Pear (Zhujiang) River, Canton Tower stands across from the new main central business district of Guangzhou and creates a visual axis through the center of the city’s tallest skyscraper cluster. The axis begins in a park space to the south of the tower footprint and travels northward, crossing the river and running through the center of a large rooftop park spanning the top of a subterranean mall ringed with high-rise buildings. Continuing northward, the axis passes through additional open spaces, bisects a stadium and ends at CITIC Plaza, Guangzhou’s first supertall building, completed in 1996.

Canton Tower was constructed as a composite tube-in-tube design, featuring a reinforced concrete core containing all of the tower’s services and vertical transportation which is then set inside an outer structure made up of a steel lattice. The two structural components then frame a series of smaller structures suspended within the tower at different elevations. The smaller structures contain occupiable spaces with elliptical floor plates which rotate in orientation over the height of the tower. The rotation is then expressed to the outside of the tower through the twisting form of the steel skeletal structure, further emphasized through tapering inward to midpoint before expanding outward towards the uppermost levels. The roofs of the smaller structures within the tower have publicly accessible skygardens, allowing visitors to experience the variations of weather at different heights while serving as outdoor observation decks.

The slender form of the tower’s design makes it especially vulnerable to sway on windy days, creating the possibility for stresses on the structure and uncomfortable conditions for the occupants. As such, the design required the inclusion of a tuned mass damper system, the final compilation of which is comprised of a hybrid mass damper utilizing two 650 ton water tanks supplemented by motorized active mass dampers working in synch as the structure begins to move.

After sunset, the entire structure is illuminated in a light display of changing colors through an integrated system of LED fixtures; ensuring Canton Tower is a highly visible feature of the Guangzhou skyline during the day or night.
