What if it rains at the Bird's Nest concert?

Beijing Bird's Nest Stadium has a roof, so it doesn't matter if it rains.

The design of Bird's Nest Gymnasium takes into account the external rain, so it has a complete set of drainage facilities. The rainwater on the surface of the building will be discharged smoothly through the drainage pipe to avoid the problem of water accumulation. In addition, the roof of the Bird's Nest is normally open-air, but it will start automatically in rainy days. The ceiling consists of two semi-circular parts, which can be closed automatically to protect athletes and spectators in the venue from the rain.

The design of the ceiling has a certain inclination, and the edge is also equipped with a drainage system. Rain falls on the ceiling and will flow down the inclined plane and be discharged through the drainage system. Therefore, even if it rains, the whole Bird's Nest Stadium will not be affected, and it will not become a "water nest", but only "get some water".

The design features of Bird's Nest Stadium are as follows:

1, unique appearance: The appearance of the Bird's Nest Stadium adopts a unique steel structure design, showing a bird's nest shape, hence the name Bird's Nest. It is one of the largest steel structure stadiums in the world, with strong visual impact and recognition.

2. Complicated structure: The structure of Bird's Nest Stadium is very complicated, consisting of a lot of steel bars and concrete. The large-span and large-space design can accommodate a large number of audiences and hold various large-scale activities.

3. Inspiration comes from China culture: The design of Bird's Nest Gymnasium is inspired by the bird's nest and rattan structure in China traditional culture. It combines modern architectural technology and traditional cultural elements, showing the unique charm of China.
