Buttressed Core
Buttressed core is a structural system for high buildings, consisting of a hexagonal core reinforced by three buttresses that form a Y shape. Properties 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. 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.Higher and Higher: The Evolution of the Buttressed Core

Structural System
A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space. Load-bearing Buildings, aircraft, skeletons, anthills, beaver dams, bridges and salt domes are all examples of load-bearing structures. The results of construction are divided into buildings and non-building structures, and make up the infrastructure of a human society. Built structures are broadly divided by their varying design approaches and standards, into categories including building structures, ar ...

Buttress
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the ...

Samsung Tower Palace 3 – Tower G
Tower G, or simply Tower Palace Three, is a 73-Storey, floor luxury residential skyscraper in Seoul, South Korea. The structure was originally designed to be 93 stories high, but was later scaled down due to zoning rights imposed by city regulations. A notable feature of this structure is the implementation of the Y-shaped tripartite floor geometry which maximizes views and floor space. This innovation pioneered the way for the development of the buttressed core, which is used in the floor plan of the Burj Khalifa as a result of its potential application in megatall skyscrapers. It was the tallest building in the country in 2004 but was surpassed in height by the Northeast Asia Trade Tower in Incheon when it was Topping out, topped out in 2009. It was designed by United States-based architectural firm Skidmore, Owings and Merrill. The building is high. Its shape is formed by three oval lobes joined together.

Jeddah Tower
Jeddah Tower ( ar, برج جدة), previously known as Kingdom Tower (), is a skyscraper construction project currently on hold. Located on the north side of Jeddah, Saudi Arabia, it is planned to be the first tall building, and the centrepiece and first phase of a development and tourist attraction known as Jeddah Economic City. There was steady progress, but in January 2018, building owner JEC halted structural concrete work with the tower about one-third completed due to labor issues with a contractor following the 2017–2019 Saudi Arabian purge. The design, created by American architect Adrian Smith, who also designed the Burj Khalifa, incorporates many unique structural and aesthetic features. The creator and leader of the project is Saudi Arabian prince Al-Waleed bin Talal, a grandson of Ibn Saud, and nephew of the Kings of Saudi Arabia after Ibn Saud.
