Structural system for high buildings
A buttressed core is a structural system for high buildings, consisting of a hexagonal core reinforced by three buttresses that form a Y shape.
Properties
A cross-section of comparisons of various towers, from ground level from top to bottom: Burj Khalifa , Taipei 101 , Willis Tower , and the original World Trade Center
The buttressed core supports itself both laterally and torsionally. It also eliminates the need for column transfers, and moves loads in a smooth path from the building's top into its foundations.
Origin
The buttressed core was invented by the Skidmore, Owings & Merrill engineer
Bill Baker . [ 1]
It was first used in Tower Palace III in Seoul but its ability to support higher buildings than ever before was first demonstrated in Burj Khalifa in Dubai .[ 2]
Uses
Advantages
The buttressed core structural system offers several advantages over traditional methods:
Stability: It provides excellent resistance to lateral forces, such as wind and seismic activities, enhancing the overall stability of the building.
Efficiency: The system allows for a more efficient use of materials, reducing the overall weight and cost of the structure.
Flexibility: It enables architects and engineers to design taller and more slender buildings without compromising on structural integrity.
Aesthetics: The Y-shaped design offers unique architectural possibilities, contributing to the visual appeal of skyscrapers.
Disadvantages
Despite its benefits, the buttressed core system also has some drawbacks:
Complexity: The design and construction process can be more complex and require specialized knowledge and skills.
Cost: Initial costs may be higher due to the need for precise engineering and high-quality materials.
