6. Project: Concept inspired by old Chinese art concept
China's leading artists Ai Weiwei
Sweeping lines arranged around a circular vessel.
Inspired them to push the limits.

7. construction
Jacque Herzog:"A new place compared to Paris's Eiffel tower which was made for an event but then became an icon of the city"
People can go in and go out , use the space
Chinese people love to use public space

8. Problematic !
Plan
Beijing is located in an earthquake zone
Olympic standards: giant screens, shops and great views of the field and of course the safety
Solution !
Steel structure
15.24 m
Concrete bowl

9. J.Parrish :"the very first step in designing a building is to look at its heart :the seating belt"
each seat is going to be as close to the action as possible
Distance from center to seats equals 142 m
Intimacy
Motivates the athletes

10. Steel structure
24 beams in the form of trusses encircling the concrete bowl
The stadium is earthquake proof
1,000 tons each

12. Steel structure
a second set of beams fills in the empty spaces of the beams of the first set
they link all the beams to form a braided structure.

13. Steel structure
Beijing Bird’s Nest is designed to withstand earthquakes rated at 8.0 on Richter Scale.

14. Steel structure
a third set of beams support the stairways that connect the multiple levels and provides a frame for the roof membrane covering

15. Steel structure

16. Structure = façade = roof = space
Elevation
The structural elements mutually support each other and converge into a spatial grid-like formation, in which façades, stairs, bowl structure and roof are integrated.

17. The massive steel structure resists lateral loads
The load is broken down through the lattice of steel while being weakened

18. The core portion of the building carries the dead load of the concrete structure as well as the live load of people totaling to 13,122 tons.
Section
The load is transferred directly to the plinth foundation as distributed load as shown below.

19. Roof
The loads at each intersection are split between the members and transferred downward
The red points indicate the transfer connections were load impact is felt most significantly. 

20. Sustainability in the project
The Stadium uses geothermal energy to chill and heat the water that runs through the HVAC system
the piping to do that is located beneath the main athletic field.

21. Sustainability in the project
maximum amount of natural lighting as possible

22. Sustainability in the project
ETFE Panels
This membrane provides rain and wind protection. It also saves energy
Sunshine filters through the roof to light the building
keep the noise in

23. Conclusion
 Initially I thought this stadium boasted an iconic design, and after finding out all of the technical innovations that went into it, I believe this is one of the most overall creative buildings I’ve ever seen
I learned that when building systems work together in more than one way, the building itself becomes more extraordinary. From what I understand, the design idea started from ceramics and evolved into a “bird’s nest”.
