The Shanghai stadium adopts bolted ball joints, with strong applicability of the grid frame, high degree of standardization, and convenient installation and transportation.

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.
2. TheShanghai Gymnasiumis located inthe southwestern areaof Shanghai,opposite the famous
Huating Hotel. It is now called ShanghaiGrand Stage. It was completed and used in1975.Themain hall is
circular,33meters 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 1,250square meters was added with
advanced facilities. It is currentlythe first theater-style gymnasiumin China.It can undertakevarious
theatrical performances, large-scale sports competitions, assemblies, large-scale exhibitions, etc., andthe
audience capacity can still bemaintained at about 12,000.

4. 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
9. 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
10. 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.
