Zhongguancun Financial Center is located in the west zone of Zhongguancun, Haidian District, Beijing, consisting of tower, wing and connecting corridor. Both the architectural plane of the tower and south and north elevation are arc-shaped. The tower comprises 4 underground floors and 35 floors on the ground, with floor area of about 79,318㎡. With enclosing structure entirely being glass curtain wall and 150m high in total, it is now the highest building to the west of the central axial line of the capital city. Its shelter floors are 12th floor and 24th floor of the building. At the elevation of 27.000m, the tower is connected with the connecting corridor bridge nearly 30m wide. Between the 6th and 7th floor of the tower, sliding vibration-isolation steel footing is installed to bear the vertical load of the connecting corridor.

Both the architectural plane of the tower and south and north elevation are arc-shaped. The south and north elevation is formed two arcs at a radius of 750m and the center of the circle 50m above the ground. The boundary of the south and north side of the architectural plane is formed by arc at a radius of 93~100m, which varies with the height of the building, forming a peculiar curve shape. The east and west side of the plane is fold line shaped, and the core on the middle is slightly rectangle shaped.

Structural shape selected and design features of the Center:

The tower of Zhongguancun Financial Center is of steel frame-support structure, and its lateral force-resistance system is composed of braced core frame and surrounding frame.

Among the core, eleven central braces are installed in total, including 5 braces on the east and west and 6 ones on the north and south.

I. Design features:

a. The lower floors are high, so on the bottom of structure profiled steel concrete structure and transitional floor are built to increase lateral rigidity of structure.

b. Segmental fold line-shaped steel frame columns are used as steel columns on the south and north side.

c. Floor level truss is installed on the floor where columns are bent and folded.

d. Sliding large-displacement vibration-isolation steel abutment is adopted. The two ends of steel trusses of connecting corridor of which structural systems are different are placed on the tower and wing by way of large-displacement vibration-isolation steel abutment and corresponding support system.

e. The joints of beam and column are all column-exterior connectors attached with short overhanging beam section.

II. Sizes of typical members:

a. Steel frame column is welded box-shaped steel column, which is Q345GJ steel plate used in high-rise architectural structure produced according to metallurgical industry standard YB4104-2000. From down to up, the length of side of steel column is gradually diminished from 600×600mm to 500×500mm. Main sections of the steel column of the core are 500×500mm and 500×400mm.

b. Frame beam is mainly hot rolled H-shaped steel and welded H-shaped steel, of which typical height is 700mm. Secondary beam is mainly hot rolled H-shaped steel, of which typical height is 350mm.

c. Central braces mainly include single dielectric rod brace and Λ-shaped brace, which is of welded H-shaped steel, and of which the length of side is 320mm and 370mm, respectively.

d. Common reinforced concrete beam and slab system is used for the first to third floor underground. Profiled steel concrete beam plus in-place floor slab is used for the first floor. Steel beam plus open rolled steel plate and in-place concrete combination floor slab is used for the standard floor. The typical thickness is 130mm.
