The world’s fourth highest building, the Ping An Finance Center in Shenzhen, China, has just been completed according to the Council on Tall buildings and Urban Habitat (CTBUH).
At 599m it is now officially the second tallest building in the country and the fourth tallest in the world, behind only the Burj Khalifa in Dubai, Shanghai Tower and Makkah Royal Clock Tower in Saudi Arabia.
Designed by Kohn Pedersen Fox the Ping An Finance Center is located in Shenzhen’s Fuitan Districtm the centre of the city’s business community.
The building contains over 100 floors of office space located above a large public podium, with a multi-story atrium providing retail, restaurants and transport to the city and the wider Pearl River delta region.
The CTBUH describe the form of the tower as a “taught steel cable, outstretched by the sky and the ground at once.
At the top of the tower, the façade tapers to form a pyramid, giving the tower a prismatic aesthetic.” The form is further emphasised by eight composite “megacolumns” along the building envelope that streamline the building for improved structural and wind performance, reducing baseline wind loads by 35 percent.
The façade of the building is one the project most innovative features; its use of 1,700 tonness of 316L stainless steel make the envelope the largest stainless steel façade in the world.
The specific material was chosen for its corrosion-resistance, which will allow the building to maintain its appearance for decades even in the city’s salty coastal atmosphere.
