RE: Live Load for residential home gym

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Thanks G.

It appears to be a few nautilus machines, and it'll be on a structural slab.  Designing for residential 40 psf vs. 50 psf won't impact the design too much.   But, designing for 100 psf or more might make a noticeable difference.  I don't think it's Phil and co. that'll be using it.

Hey Dave,

I think that is fine for joist design with maybe a 500lb point load allowance anywhere along the span for the free weights. More than likely, the free weight stand will be against a mirrored wall so they can watch themselves flex and pose in the wee hours of the night, making it a shear issue more than anything....but in case it's out in the middle of the room, I would do the point load allowance. I guess it depends on how much room flexibility they'd need and how many people can fit in the room. If it's just 1 or two people using the room at a time, I doubt there is a need for more than (4) 100lb dumbells on a rack.

Now, if it's the Margera Family weight room, then maybe 125 psf live load is a reasonable assumption. :-)

David, although 50 psf is sounds reasonable however, the magnitude of the point load is quiet big especially if you are talking

Bowflex, Weight rack, etc as your gym equipments. I suggest disregarding the descriptive word "home" and focusing the word "Gym" would eliminate the confusion. In my opinion a 150 psf plus a concentrated load of 1000 lb. would be ideal for this kind of application.

50 psf LL sounds reasonable for a home gym.  Or am I way off?  Any advice would be appreciated…  TIA
