Therapy Swings - Design Load?
Therapy Swings - Design Load?
(OP)
Does anyone know of any IBC 2006 design load requirements for special indoor equipment that will be hung from the roof structure of a classroom? I need to design for therapy swings in a special needs classroom, but I can't find much information on the design requirements. I was thinking of using a 500# point load in any direction in the beam design.
Thanks
Thanks

However, if you really think the load might be applied to the roof beam "in any direction," I think I would run (not walk) away from this assignment. Just go straight to your local court house, because that's where you'll end up if that loading orientation ever happens. Is this a therapy swing (5 or 10 degrees about a vert. axis) or a carnival ride?

In those, for static loads, we tested to 2x working load.
For climbing treestands, subject to repetive loads (similar to swings) we tested to 10,000 cycles. If they failed either, they failed.
As for the swing, I would use a static FS=2.0 at least. I would also require testing for the repetitive loads.

I say this in the hospital when they were radiating me in all the wrong places.

I just talked to my granddaughter, who is a special ed teacher and she says they don't have any swing suspended from the ceiling. the only thing they have suspended from the ceiling is harness to help some students exercise their legs.

The manuf should give you the capacity they are looking for. I had the luxury of designing in a new facility so I could make it nice and stout. It will be more difficult if it's a retrofit. I'm out of the office right now or I'd post the cut sheet for you.
