Shanghai Tower is a 128-story megatall skyscraper in Lujiazui, Pudong, Shanghai. It is the tallest of the world’s first triple-adjacent supertall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center. With a height of 632 meters, it is the world’s second-tallest building, the world’s tallest twisted tower, and the world’s highest observation deck. The Shanghai Tower is also one of the world’s most structurally advanced buildings, featuring an innovative structural design that makes it capable of withstanding extreme weather conditions.
Design
The Shanghai Tower is designed by the Gensler architecture firm. The design of the tower is based on the Chinese symbol for “eternity,” a ring with a square hole in the center. This symbol is reflected in the tower’s unique shape, which features nine cylindrical buildings stacked on top of each other, each one slightly smaller than the one below it. The design also features a spiraling glass facade that wraps around the entire building, giving it a sleek and modern look.
Structural System
The Shanghai Tower is constructed with a series of steel and concrete structures. The steel structures are composed of a steel frame and columns, while the concrete structures consist of a reinforced concrete core and an external concrete wall. The steel frame is composed of a central core, which is surrounded by eight columns that are connected to the core. The core and columns are connected by a series of steel beams and girders. The concrete core consists of a central column surrounded by eight columns that are connected to the core by steel trusses. The external wall consists of a series of reinforced concrete panels.
Wind Loads
The Shanghai Tower is designed to withstand strong wind loads, which can reach up to 200 km/h. To achieve this, the tower features an innovative structural system that is able to absorb and redistribute the wind loads. The design features a series of horizontal steel trusses, which are connected to the core and columns. These trusses are designed to act as dampers, absorbing and redistributing the wind loads and preventing the tower from swaying.
Seismic Design
The Shanghai Tower is also designed to withstand seismic activity. The tower is constructed with a reinforced concrete core and an external wall, which are designed to absorb and redistribute the seismic forces. The design also features a series of steel columns and trusses that are connected to the core and the external wall, providing additional support and stability.
Other Features
The Shanghai Tower also features a number of other features that make it a unique and advanced structure. The design features a series of sky gardens, which are located on the upper levels of the tower and provide views of the city. The tower also features a number of energy-saving features, such as a double-skin façade and an energy-efficient lighting system. Additionally, the tower features a number of advanced safety features, such as an advanced fire detection and suppression system and an evacuation system.
Conclusion
The Shanghai Tower is an impressive feat of engineering and design. Its innovative structural design makes it capable of withstanding extreme weather conditions and seismic activity. Additionally, the tower features a number of advanced features that make it a unique and advanced structure. It is no wonder that the Shanghai Tower has become an iconic symbol of the city of Shanghai.
