What are the technical highlights of Shanghai World Financial Center?

Shanghai World Financial Center is located on the ground 10 1 floor, with a height of 492 meters, and the highest floor and roof height rank first in the world.

This design was completed by American KPF architects, which has a long-standing reputation in the design of super high-rise buildings. The combination of arc and straight line is boldly adopted, and the inverted trapezoidal wind tunnel is set at the square opening at the top, which reduces the wind pressure at the top of the structure.

The super-large building area of the low-rise area with one side of 58 meters (periphery) meets the requirements of large financial institutions, and gradually narrows to the high-rise area. The middle floor area is suitable for small office tenants, while the top floor is suitable for hotels, which highlights the integration of multi-purpose super high-rise building facilities.

2) Technical Highlights of Shanghai World Financial Center

Among the 9 1 vertical elevators in the building, 39 double-deck car elevators are used, which greatly improves the transportation capacity of super high-rise buildings. Among them, 24 are super double-decker elevators, which can automatically adjust the floor spacing and accurately stop at different floors.

The fastest elevator speed reaches 10 m/s, which is the fastest double-deck elevator in the world. It only takes about 1 minute from the underground 1 floor to the 95th floor. In addition, it is equipped with elevators, which can transport cars to high-rise areas. The elevators in Shanghai World Financial Center adopt four brands: Toshiba, Hitachi, Otis and ThyssenKrupp.

As for the power supply of the building, the 35 kV three-way substation equipment ensures stable power supply and has enough capacity to meet the needs of tenants for additional power supply. In terms of emergency power supply, in addition to the emergency generators used in the building, four spaces are reserved for installing 1 500kVA tenant-specific generator sets and 1 500kVA generator sets.

The exterior wall adopts aluminum curtain wall with multiple layers of glass to improve the energy-saving effect inside the building. The number of curtain walls used in the building reaches 10 and 6 18 groups (equivalent to about 40,000 pieces of glass).

Safety and seismic performance of Shanghai World Financial Center

1) Structural Design of Shanghai World Financial Center

The structural design of Shanghai World Financial Center was entrusted to the American LERA structural design company, which enjoys a world reputation in the field of high-rise building structural design, and its reliability was greatly improved.

The core of Shanghai World Financial Center adopts the core tube of reinforced concrete structure and the peripheral mega-structure composed of mega-columns, ribbon trusses and diagonal braces, which are connected by outrigger trusses to improve the seismic and wind-resistant safety performance.

Main frame structures, such as peripheral mega-structures, are composed of flexible steel members and high-strength concrete. ArcelorMittal and Baosteel are two major steel suppliers.

There are 2,2765,438+0 pile foundations buried in the underground part, which are covered with 4.5-meter-thick pressure plates to support huge buildings. The longest pile foundation is about 78 meters and weighs 17 tons. The total weight of steel pipes used in these piles is about 20,000 tons. If all pile foundations are connected, its length will reach 88.67 kilometers.

In order to reduce the shaking of the building caused by strong wind, two wind dampers composed of counterweight weighing 150 tons were installed on the 90th floor of the building to ensure the habitability and comfort of the building in strong wind.

2) Seismic performance and measures of Shanghai World Financial Center.

For a long time, the architectural design standard of Sen Mansion is one level higher than the ordinary standard. The design of Shanghai World Financial Center fully meets the building seismic standards of China and has sufficient seismic performance. Moreover, the seismic performance has been improved to the extent that it can continue to be used even after the earthquake.

In China, the seismic standards of buildings set in different regions are different, while the standard set in Shanghai is a 7-degree earthquake. The experimental results of 1: 50 model show that Shanghai World Financial Center can resist earthquakes of magnitude 8 ~ 9.

In addition, for long-term ground motion, Shanghai World Financial Center is equipped with pendulum detection device. When long-term ground motion is detected, the elevator will stop at the nearest floor as needed to safely evacuate people in the elevator.

3) Safety measures

You need a security door to enter the office area on floors 7-77 of Shanghai World Financial Center. In addition, all office floors are equipped with the most advanced IC card access control system.

For each tenant's visitor, the system of registering the visitor's name in advance is adopted to allow the guests to pass quickly and smoothly. A system that meets the safety requirements of international financial centers and ensures the safety of business activities of multinational financial institutions.

The disaster prevention center of the building adopts the central management system of the building, which effectively controls the 24-hour security, access control system and video monitoring device, and constructs a foolproof security system from both human and machine aspects.

In addition, for tourist halls where the number of visitors is expected to exceed 3 million per year, metal detectors are installed at the entrance to check the articles held by tourists as appropriate to ensure the safety of tourists and buildings.

4) Disaster prevention and escape plan

The building grade of Shanghai World Financial Center is Class I, the building fire protection is classified as Class I building, and the fire resistance rating is Class I. Because the height of the building reaches 492 meters, the special fire protection measures adopted in the fire protection design have been specially demonstrated by the national fire department.

There are 7 floors (18, 30, 42, 54, 66, 78, 90) in the "refuge square floor" in the building. The smoke is prevented from entering the refuge square floor by the pressurized smoke prevention system to ensure the safety in case of disaster.
