The bridge that must legally wobble

  • Publicado em 17 Abr 2022
  • "Daly's Bridge", in Cork, Ireland, is better known as the Shakey Bridge. Because it shakes. But what happens when a bridge like that has to be repaired and refurbished? • Thanks to Cllr McCarthy: his site is corkheritage.ie/ !
    Edited by Dave Stevenson davestevenson.co.uk
    A thorough study of how the Bridge shakes: publish.ucc.ie/boolean/pdf/201... [PDF]
    I did try (a lot!) to get an interview with someone from RPS Group, who were in charge of the refurbishment, but I just wasn't able to make contact. However, I'm indebted to Michael Minehane, principal engineer, whose talk to Engineers Ireland gives a lot of in-depth information about the bridge was refurbished! You can watch it here, along with Cllr McCarthy's history of the bridge: www.youtube.com/watch?v=j52po...
    Thanks to Youssuf Radwan for the suggestion!

    Current era: "We need to hire engineers, surveyors, fabricators, it's gonna cost about 10 million euros."
    A hundred years ago: "Dude, we can order a bridge from this catalog. 700 pounds."

      @hausaffe and they screw up too.
      locally they replaced a bridge across a small river, a bit wider than the river in the video, they used a government approved design that was in use for decades and hired experienced engineering company to do the work .
      after a year the driving surface was cracked and warped and the transition from bridge to land was heaving amd sinking.
      Turns out that design of bridge had never been used over water.. even though all the authorities and know it alls said it was approved.

      Government: It's a heritage site mate, it has to be preserved in its initial condition
      Engg. Coy: Really? Is the wobble important?
      All the people: WE WANT THE WOBBLE

      @flexiblebird In all fairness, if you build something expensive thats built to last, its probably gonna be unique in alot of ways, aka quirks, now that means those quirks 90 years from now have to be accounted for, dealt with, all the while the dickheads who built the thing 90 years ago just said to themselves, “if it works for 90 years then when it does break itll be some other assholes problem hope theyre prepared”.

    • Dex
      Dex 2 meses atrás +3

      @mmw computers to run the simulations cost money, the electricity flowing through the computer center costs money, and the developers who made the simulation need to be paid for their work and equipment. Costing more than 50k actually isn’t impossible, although the amount of money spent is probably lower than 50k because they probably used already existing software and hardware.

    That bridge has a sibling in my home town of Shrewsbury! The bridge that goes over the river Severn from the quarry to the boathouse pub was built by the same company and wobbles possibly more than this one does. Looks almost identical too but ours is green (last time I saw it anyway)

      Porthill Bridge. It even has its own Wikipedia article, which says: "Porthill Bridge experiences significant vibration, even when few people are crossing it - and has done since it was installed. Local pedestrians mostly accept this eccentricity as part of the bridge's charm."

    Shaky bridges are great. I remember many years ago when I was at school going across a suspension bridge in Scotland with a few friends. We decided to see what would happen if we walked in step. I think we managed about 3 steps in unison before realising just how bad an idea it was. It's really amazing how quickly the feedback builds up if you manage to match the resonant frequency of a bridge.

    • Neurofied Yamato
      Neurofied Yamato 2 meses atrás +1

      ​@A B You probably mean the Broughton Bridge collapse, which while the marching contributed to the collapse, the bridge was poorly constructed and failure was actually found to be inevitable. That led to breaking step when crossing bridges in the British and French armies. In France, marching at the Angers bridge's resonance frequency is only partially the cause of collapse too. The soldiers were actual already ordered NOT to march in cadence when crossing. But the bridge was poorly maintained and there was heavy winds. The various loads were the primary reason why Angers bridge collapsed so in both cases it was multiple contributing reasons.

    • A B

      Not sure if you're aware, but a French bridge collapsed after soldiers marched across it.

    Many years ago I was involved with ensuring the safety of a somewhat similar bridge. (A similar span but much wider, built for use by ponies and traps.) It was reported that it was bouncing to the extent that some pedestrians were concerned, so I calculated its natural frequency of vibration, as part of my investigation. The number I got was about two Hz (cycles per second), which is about normal footfall frequency for someone walking. This meant that someone walking at a steady pace that closely matched the natural frequency would set the bridge bouncing in just the same way as someone repeatedly pushing a child on a swing to make them go higher.
    Anyway, I could report that there was nothing to worry about, as long as a platoon of people marching in step didn't try to cross it.

      At one point, you could order single family dwellings from a Sears and Roebuck Catalog. The entire house would be packaged in a couple of boxcars and shipped to your town or city, where your contractor could pick up the materials and assemble your new home.

      @MLeoDaalder I'm not familiar with Sears, but in the 60s you could order houses from Quelle (in Germany). There is one in a museum (Freilichtmuseum Kommern) in a state very close to its original, that one can enter and look around.

      @DECODED The sears house catalogues started well before the 1900s and were big around then and a bit after ww1 for repayment to soldiers and their families with farming land (atleast was done alot here in Australia to returning soldiers even in ww2 had a similar premise). More to do with mass migration to areas around a country, either farming land, industrially wealthy towns or on the outskirts of a city or major transport artery. Shame theres nothing like it now outside of preordered granny flats and sheds due to companies and cities monopolising on houses and even regulstions (some understandable, most just ridiculous)

    I am currently taking a class in vibrations and all throughout the video I was thinking “oh no it’s gonna be another Tacoma Bridge incident”, but I was pleasantly surprised to find out that the engineers intentionally left in the vibrations! I assume that since this bridge is on a much smaller scale when compared to the Tacoma Bridge, the engineers were able to get away with integrating the vibrations instead of damping them. Super interesting stuff!

    All suspension bridges move to some extent. Walking across the Brooklyn Bridge on a windy evening I can feel it move. The Tacoma Narrows Bridge in Washington State had a wild wobble which caused to collapse in the 1940s I believe. But for any lawyers in the viewing audience, please define a "legal wobble." I can see an illegal wobble by standing outside a pub on a Friday night. Cheers!

      I've never been there, but this is exactly why the bridge does indeed need to be preserved as is. As long as it's safe of course, which it already was for nearly a century, so that seems easy enough. If this bridge would've been identical looking but not wobbly anymore, it would straight away lose all its appeal. It's not a good looking bridge, so its one standout feature is the wobble. And if I'm somewhat in the area, this might be a fun little trip to take on holidays, but again: not if the wobble wasn't there.

      If you think that is unnerving - there is a walkway (a glass floor "bridge" over a deep ravine) I think in China where one part is actually a screen (-like) that shows a shattering of the glass floor when someone walks on it, complete with sound.

      @Michiel Werring No, the cork museum is in the Algarve in Portugal and I have visited it. Cork trees do not grow in Ireland.

    A few years back I lived in a small town (village?) in Western Norway. Down at the beach where the local river goes into the fjord, there's a small forested area with a short suspension bridge over the river. That thing swings and bounces like an amusement park ride, so much so that my dog was terrified of walking across. Kids like to prank each other by promising not to shake the bridge, and then jumping like crazy. You can really lose your balance if you're not expecting it.
