Large-span space frame structures stadium building

1
Large span structure

• Buildings of various structural forms that span
  a space of more than 60 meters horizontally.
  Large-span structures are mostly used in civil
  buildings such as theaters, stadiums, exhibition
  halls, assembly halls, airport terminal halls and
  other large public buildings, large-span factory
  buildings, aircraft assembly workshops, and large
  warehouses in industrial buildings.
• structure type
• There are folded plate structure, shell
  structure, grid structure, suspension cable
  structure, inflatable structure, tent tension
  structure, etc.

Shanghai Stadium
The Shanghai Gymnasium is located in the
southwestern area of Shanghai, opposite the
famous Huating Hotel. It is now called Shanghai
Grand Stage. It was completed and used in 1975.
The main hall is circular, 33 meters high, with a
roof grid span of 110 meters in diameter, and can
accommodate 18,000 spectators. After renovation
in 1999, a double-deck stage of 1,250 square
meters was added with advanced facilities. It is
currently the first theater-style gymnasium in
China. It can undertake various theatrical
performances, large-scale sports competitions,
assemblies, large-scale exhibitions, etc., and
the audience capacity can still be maintained at
about 12,000.

Structural system
The space frame structure is a circle with
a diameter of 124.6 meters and is supported by 36
pillars evenly distributed on the circumference
of the 110 meter diameter circle. The support
point is cantilevered by 7.30 meters, and there
is a gas tower in the middle of the grid. The
height of the grid is 6 meters, the middle arch
is 2.5 meters, and it is composed of more than 1
1 400 16 manganese seamless steel pipes and more
than 90 steel balls. The total design weight is
60 tons

  of 36 swinging
• Seat support.

Classification

• According to its own structure, single layer,
  double layer, three layer, single layer
• According to the construction materials, it is
  divided into rigid grid frame, aluminum space
  frame, wooden space frame, plastic space frame,
  reinforced concrete space frame and combined grid
  frame
• According to the support situation, it is divided
  into peripheral support, four-point support,
  multi-point support, three-side support,
  opposite-side support and mixed support

Space Truss Structure

• Use a relatively common large-span roof
  structure. This structure has strong integrity,
  good stability, large space rigidity and good
  shockproof performance. The height of the net
  frame is small, and smaller rod-shaped components
  can be used to assemble a large-span building,
  effectively using the building space. The
  large-span grid structure suitable for industrial
  production can be divided into two types flat
  grid and shell grid, which can adapt to a variety
  of flat shapes such as round, square, and
  polygonal. Flat-shaped grids are mostly
  double-layered, and shell-shaped grids are
  divided into single-layer and double-layer, and
  there are single-curve, hyperbolic and other roof
  forms.
• In the late 1950s, Shanghai Tongji University
  once built an assembled monolithic reinforced
  concrete single-story joint square shell
  structure. The clear span of the hall is 40
  meters and the outer span is 54 meters. The
  reconstruction design of Shanghai Cultural Square
  adopts the steel structure spherical joint flat
  slab grid frame, which was completed in 1970.
  The New Orleans Gymnasium, built in 1976, has a
  circular plane diameter of 207.3 meters and is
  the largest steel grid structure building in the
  world today.
