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 94th , 97th ,and 100th 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."[8] 19
