The Princeton Bridge

I don't know any of the particulars of this bridge in London, only that I like it. ('The Shard'- Renzo Piano in the background.)

It's called the Millenium Bridge, and they initially got the design wrong
They fixed the problem (see below), and now it's a London landmark.
For the mathematically inclined:
The conclusion of the study:
"The introduction of damping by a combination of frame-mounted viscous dampers and tuned-mass vibration absorbers has cured the London Millennium Bridge’s famous wobble. It was caused by synchronous lateral excitation from pedestrians, a phenomenon that was not well-known at the time but for which there is now a good understanding and good data."

Thanks for that. Wobble again.
Google image search is fruitful.

The bridge opened on 10 June 2000. For the opening ceremony, a crowd of over 1000 people had assembled on the south half of the bridge with a band in front. When they started to walk across with the band playing, there was immediately an unexpectedly pronounced lateral movement of the bridge deck. This movement became sufficiently large for people to stop walking to retain their balance and sometimes to hold onto the hand rails for support. Video pictures showed later that the south span had been moving through an amplitude of about 50 mm at 0.8 Hz and the centre span about 75 mm at 1 Hz approximately. Probably higher amplitudes occurred periodically and several modes were involved. It was decided immediately to limit the number of people on the bridge, but even so the deck movement was sufficient to be uncomfortable and to raise concern for public safety so that on 12 June the bridge was closed until the problem could be solved. It was not reopened to the public until 22 February 2002.

The Millenium Bridge opened on 10 June 2000 as London's first new Thames crossing in more than 100 years. This modern 320m long structure was designed by the architect Sir Norman Foster with sculptor Sir Anthony Caro and engineers Arup. This whole project cost 18 million pounds for construction and 5 million pounds for various modifications. It was opened by The Queen.

I believe there is a bridge in Russia over the Volga River that suffers from the same phenomena.
But I don't think it is as elegant as this structure. -
The Millennium Bridge in London cost many many millions and some more millions to fix it !
Our Millennium Bridge over the Tyne, which is not far from where I live, cost just about as much as the repairs to London's ... and it is, I think better.
It's hinged so that it can tilt up to let ships pass below it...

yikes.... The low res video is very helpful in understanding this one. I wonder what the overall project was.

May not be fine design, but this is simple, cheap and clever.

It is absolutely brilliant!

Solo, how do you turn it off? -

Hi, dale:
Did you see the lengthy debate about that refrigerator on the website link you provided? -

Hi, dale:
Did you see the lengthy debate about that refrigerator on the website link you provided?Yes, the energy debate.
I followed a few other links on this, and I think the idea of bioluminescence providing the energy, is an interesting concept, this being of course a living organism.
Now how it achieves its "food" for providing the energy, and whether they can produce enough energy is the question.
I do however really like the "out of the box" thinking at Electrolux. Their competitions are always interesting. -

this really should be in the funny pics thread but...
