View Full Version : BIOMECH-L: Vibrations from the icicle - will they be important?

Dear members,
On a site less than 10 metres from our clinical gait lab at Guy's Hospital
in London there are plans to construct the tallest building in Europe. The
architectural realisations depict a huge chard of ice pointing towards the
heavens (apologies to humanists/atheists). The building at 62 storeys with a
large radiator on top (the last word in Eco-design) will be twice as tall as
our hospital (the tallest hospital in Europe).
Necessarily, there will be considerable noise, traffic disturbance and dust,
but our main problem will come from the vibrations of the building work. I
understand the concrete pillars that form a part of the base of the building
will be helically-driven to reduce vibration pollution.
I like vibrations as much as the next person except when they interfere with
my equipment! My questions are:
If the magnitude of the vibration at source was known, could we estimate the
level of vibration within our laboratory given some material specifications?
What level of vibration would interfere with the operation of our
cameras/forceplates (some cameras are fixed to plasterboard, others are on
tripods)?
Would long-term vibrations have a deleterious effect on our gait lab
equipment?

We are in the process of making a representation to the local planning
committee and need as much information as possible to construct a case. I
know it's not a Biomechanics question but I'd be grateful for your thoughts.
