ARCHITECTURAL INFORMATION The most distinctive feature of the SWFC's design is the trapezoid aperture at the peak. "Chinese mythology represents the earth with a square and the sky with a circle.” It also resembled a Chinese Foreigners and Chinese alike informally refer to the building as the bottle opene The tower features three separate observation decks . Located on 94 th , 97 th ,and 100 th floor

Plan form of building "Chinese mythology represents the earth with a square and the sky with a circle.” The building will be mixed-use, with a museum at the base, a hotel at the top, and office spaces in between. Above the hotel will be a visitor’s center , while much of the area below grade will house mechanical parking.
Structural Detail The tower's trapezoid aperture is made up of structural steel and reinforced concrete. A large number of forces, such as wind loads, the people in the building and heavy equipment housed in the building, act on the SWFC's structure. These compressive and bending forces are carried down to the ground by the diagonal-braced frame (with added outrigger trusses). The design employs an effective use of material, because it decreases the thickness of the outer core shear walls and the weight of the structural steel in the perimeter walls
Exhibit Braces and Outriggers are used to stabilize and support structures to ensure extra support. The Exhibit and Display Braces are used to stabilize or support a corner span of truss that may need extra strength. Whereas our Display Booth Outriggers are an angled piece of truss that slopes back or in front of a vertical upright / leg providing the necessary
This is an extraordinary building, one that will attract the eye of all in Shanghai. Making use of a composite, steel and concrete mega-structure While no two floors are identical, considerable repetition is found in the concrete walls and steel framing. In order to decrease the weight of the building, the majority of that decrease had to be found in a reduction of the thickness of the concrete shear walls of the services core. This reduction could be achieved only by decreasing the wind- and earthquake-induced lateral forces
Column of mega structure The columns of the mega-structure are of mixed structural steel and reinforced concrete the steel column must be of a size capable of fully transferring the vertical component of the load in the diagonals to the composite columns
The steel column only needs to be strong enough to carry the construction load of the steelwork above. HOW TO MAKE BUILDING EARTHQUAKE RESISTANCE :- Because of the unusual nature of the structural system, considerable attention was given to resistance to the moving earth. The structure is designed to remain in the elastic mode throughout the life of the building.

AWARDS :- Shanghai World Financial Center was named by architects as the best skyscraper completed in 2008, receiving both the Best Tall Building Overall and Asia & Australasia awards from the Council on Tall Buildings and Urban Habitat (CTBUH). [19][8] CTBUH's Carol Willis, head of New York's Skyscraper Museum , stated: "The simplicity of its form as well as its size dramatizes the idea of the skyscraper." [8] Architect Tim Johnson noted its innovative structural design: "Steel trusses gird against the forces of wind and earthquake and made the building lighter, made it use less steel, and contributed to its sustainability."
