1 Is this a manufactured structure or a natural structure. Explain why
Is this a manufactured structure or a natural structure? Explain why! (if your question does not suit either type of structure, explain why, demonstrating you know what manufactured and natural structures are) Is this a mass, frame, or shell structure, or hybrid? Explain why! (again, if your question does not suit this explanation, explain why, demonstrating that you know what mass, frame, shell, and hybrid structures are)

7 The Sydney Opera House Patrick 7BE

8 Big Question Is the Sydney Opera House a Wonder of the World or a World Heritage site? Find out at the end!

9 Is this a manufactured or natural structure?
The Sydney Opera House is a manufactured structure. It was built by humans. The Sydney Opera House was built in Sydney, Australia. It is not a natural structure because it wasn’t natually formed or made by a different animal.

10 Mass, Frame, Shell, or Hybrid?
The Sydney Opera House is a Hybrid of a Mass and Shell structure. Shell because it can seat 5,738 people, and mass because it combines similar materials into a certain shape or design. It’s also really big.

11 What is the function? The Sydney Opera House is a multi-venue performing arts centre, so the building could have multiple functions. The Sydney Opera house could hold plays, musicals, and concerts.

12 What are the materials used?
Precast concrete panels supported by precast concrete ribs (for the shells) Glass (windows) Pink granite (exterior) Off-form concrete, Australian white birch plywood, brush box glulam (interior surface treatments) Various lights, (interior) and electric cable, and some steel cable.

13 Cost The total cost in this structure is $102 million, which is equivalent to $915 million in 2015! Here's the details: Stage I: podium from Civil and Civic Ltd approx. $5.5 million. Stage II: roof shells from M.R. Hornibrook (NSW) Pty Ltd approx. $12.5 million. Stage III: completion from The Hornibrook Group $56.5 million. Separate contracts: Stage equipment, stage lighting and organ $9.0 million. Fees and other costs: $16.5 million.

14 Aesthetics The building looks nice alone with the
huge shells, interior, and the exterior, but the shells can be decorated as seen in the picture above, and the building also glows at night.

15 Video Start Time: 1:00 Stop Time: 2:00

16 Failure Because the Sydney Opera House is built above water, after a long period of time the concrete/whatever material is below the structure might wear down, crack, then break under the mass of the opera house, resulting in the structure sinking into the ocean. Other than that, the Sydney Opera House is pretty stable and most likely won’t be breaking down soon.

17 Construction Stage The Sydney Opera House was built by
Jore Utzon. His construction team thought it would take 4 years to build. But it actually took 14 years, from The “Shells” themselves took 8 years to built. 10,000 builders were employed to work on the building.

18 Size The Sydney Opera House has a total
of 1000 rooms. They change more than 15,500 lightbulbs each year. The largest concert hall in the building holds 2,679 people. 8 huge airplanes can sit wing-to-wing on the site.

19 Geometrical Shapes found on the structure
Some geometrical shapes found on the structure are: semi-circles, fourths of ovals, full circles, rectangles, squares, triangles, and a couple of cone shapes.

20 Safety The Sydney Opera House most likely has fire extinguishers, emergency exits, fire alarms, smoke/carbon monoxide detectors, sprinklers, eyewash stations, fire alarm pull stations, drench hoses, emergency shower units, and emergency escape plans. Since I couldn't find any safety info on the Sydney Opera House, I based this on regular building safety plans.

21 Forces A force acting on the Sydney Opera House itself could be compression because of all the people on it and of gravity acting on it. That could also be the same for the seats, since people sit on them. Since I couldn’t find any other information, here’s an explanation on the forces: -Tension: pulling a materials ends apart. -Compression: crush a material by squeezing it together. -Shear: bend or tear a material by pressing different parts in opposite directions at the same time. -Torsion: twist a material by turning the ends in opposite directions.

22 Foundations The Sydney Opera House is supported on 588 concrete piers sunk as much as 25 metres (82 feet) below sea level.

23 Big Question Is the Sydney Opera House a Wonder Of The World or a World Heritage Site? Both! The Sydney Opera House is part of the Seven New Wonders of the World and was made a World Heritage Site in 2007.
