2. Introduction:

3. Brief history about Herzog & de Meuron:

•Year of birth : 1950 both•Nationality : Swiss•Education : Swiss Federal Institute of Technology (ETH) in Zürich• Awards :

I. 2001 Pritzker PrizeII. 2009 Lubetkin Prize for

the Beijing National Stadium

•Selected projects:I. 2000 Tate Modern,

Bankside, London, UKII. 2005 Allianz

Arena football stadium, Munich

III. Beirut Terraces, Beirut, Lebanon

Project:conceptConcept inspired by old Chinese art

Sweeping lines arranged around a circular vessel.

China's leading artists Ai Weiwei

Inspired them to push the limits.

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

PlanProblematic !

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

Concrete bowl

15.24 m

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

Steel structure

24 beams in the form of trusses encircling the concrete bowl

The stadium is earthquake proof

1,000 tons each

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.

Steel structure

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

Steel structure

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

Steel structure

Elevation

Structure = façade = roof = space

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.

The massive steel structure resists lateral loads

The load is broken down through the lattice of steel while being weakened

SectionThe 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.

The load is transferred directly to the plinth foundation as distributed load as shown below.

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. 

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.

Sustainability in the project

Sustainability in the project

maximum amount of natural lighting as possible

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

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”.
