Thanks everyone for your input. I'm realizing this is far more complex than I'd imagined. Will try finding an engineer who can work within a public art budget.
But first, I think BAretired misunderstood the 500# starting point. I mentioned 500# max working load for cable rigging design, so each...
Consensus seems to be my 4" tube is not beefy enough. What size and gauge stainless do you folks recommend?
I totally agree people will climb on this thing, half my friends would. :)
Thanks for your replies! Questions:
1) BAretired is concerned the 4" OD x 11 gauge stainless steel beam will not be sufficient. If I bumped that up to 13 gauges would that suffice? If not, what is suggested?
2) I had not considered pre-tensioning the cables. I'd appreciate pointers on the...
Hi Everyone. Safety and structural engineering question for you experts.
I'm designing a structural frame for an outdoor public art display. Two vertical steel cables will be tensioned from a horizontal metal rail down to concrete flooring 8 feet below. The two cables have about an 8" gap...
EdStainless The overhead steel will most likely be stainless, though I may end up going with powder-coated steel instead. Help me understand the rust running down the cables. If I'm using stainless steel (cable and rigging, and overhead steel) and aluminum discs, where does the rust come from...
Thanks for replying everyone. Some information for you:
The aluminum disc is 5052 grade by necessity, it's the only grade used by the vendor preparing the discs.
Answering Tmoose's questions about what gets hung on the cables, let me offer more details. There are actually two cables suspending...
Hi All, hoping you experts can advise on best course to maximize longevity of a public art piece.
Details:
I have a 1/8" thick x 14" diameter aluminum disc suspended between a concrete floor and metal post above, using 1/8" metal cable. The disc has a 3/8" hole at top and at bottom, to thread...
