infinitely strong cantilever
folks...
can anyone tell me what kind of material these guys are going to make this structure out of? it must have some really good physical properties...
"will be supported by steel beams ". so contact your local steel warehouse/ fabricator.
the shadow appears to show cross braces between the inner and outer walls. my guess is the beams would be much deeper than shown in the rendering. no reason they couldn't put big knee braces below it if they so desired.
the article mentions 72,000,000 lbs capacity. i suspect this should be 72,000 lbs.
so be studying up on those curved beam equations...(see that thread in the fea forum).
its the new anti-gravity paint that they will use on the guardrails.
120 people, lets say 50,000 lbs
uniformly distributed on a ring, 70' radius
centroid is about 50'
so the bending moment at the cliff is 2.5mft.lbs
supported by two i-beams (of very large size) ...
how about cable trusses above the platform ?
nah, the contractor just put some extra toenails in that thing. don't worry, that'll hold it.

the project is still seeking an insurer, said architect david jin, who said he came up with the skywalk idea while visiting the canyon in 1996.
do we need to add anything more?
thought that might bring a chuckle to a few informed people.
just when you think one of your designs may be a bit hokey... this will always serve as a baseline of hokeyness... lol

interesting. typical architect's concept that has a very thin section and a sky hook.
it's a bit of a challenge... but if you make the guardrails composite with the concrete and beef them up a tad... just a matter of doing the sums... you don't, however, want to use diagonal struts... they would have a tendency to cause the track to pull out from the cliff face... <g>

environmentally speaking - it is an outrage. visual pollution. if you want thrills, try base jumping. maybe the hualapi nation should try building a casino, out of site of the canyon. i always regarded native americans as respecting the earth, but that idea is idiotic.
isn't the solution obvious? they just need to place a couple of skyhooks at the end!
one of my mentors always used to say if it doesn't 'look right' then it probably isn't, and the proposed structure, as pictured, just doesn't look right to me.
the knee-braced solution may spoil the view through the 'glass' bottom, so i expect they'll end up with a cable-stayed structure, which will look good anyway.
