Miniature Golf Live Loads

Miniature Golf Live Loads

Miniature Golf Live Loads

(OP)
A second floor (steel beam and concrete slab over metal deck) to be used as a floor to support use as an open-to-the-public miniature golf course.
These golf courses sometimes have various types of golf holes with elevated ramps, fake mountains, etc.

Any thoughts on design loads? I was thinking of trying to calculate an approximate allowance for the "dead" loads associated with the golf course itself and then add 50 psf for live load.
Alternatively I could perhaps just use 100 psf or 125 psf and assume the golf course materials plus the people-live load would be taken care of.

I'd include self-weight of structure, MEP loads and ceiling separately.



Thoughts?

RE: Miniature Golf Live Loads

Left to my own devices, I'd have gone 100 psf live plus a reasonable superimposed dead load for plaza/landscaping sans put put. I don't see the put put stuff putting much of a dent in that.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: Miniature Golf Live Loads

I'm with Koot on the 100psf live load. I would think people will congregate in groups for photos or to 'Tee Off' in the put-put tee boxes.

The dead loads don't seem like they would be much. You could throw ~20-25psf on for that and feel good that there is some extra capacity in the live load portion of the design.

RE: Miniature Golf Live Loads

People can't stand on the heavy stuff (like windmills or clown faces) anyway, agreed with the above.

RE: Miniature Golf Live Loads

+1 for 100 psf live load, and 20 psf dead load for wood framed ramps & decorative stuff.

I would make sure the Owner understands the dead load assumed though, so they don't pour 2ft of concrete for ramps or something.

RE: Miniature Golf Live Loads

(OP)
I didn't post other photos but some min. golf sites have large "mountains" of boulders and such. I'd assume here it might be fake boulders.
Some have rivers and ponds as well but don't think that might occur in this instance.

The 20 psf allowance for golf "stuff" and 100 psf live load sounds a bit excessive but probably will go with that.

This is probably beyond your design responsibility, but I think the putt-putt business is a tough one. That floor might be re-purposed for a different use at some point in time.

RE: Miniature Golf Live Loads

(OP)
That's why I also suggested using 125 psf (light storage) as that might be the future use.

I am so jealous of You for having this Fun Job ! big smile
I'll reflect on the OP question later :D
Have Fun!

RE: Miniature Golf Live Loads

ASCE 7's live load commentary lists amusement structures at 100 psf with a footnote saying to use the actual weight of equipment when heavier. Do you have any insight on the golf course structures construction? If they are wood, it won't be very heavy. But the weight of some big concrete ramps may add up quick. If outdoors, will it have a topping slab above the waterproofing ? If not, will the holes be in the structural slab?

RE: Miniature Golf Live Loads

It's so much cheaper to use a real boulder than to build one out of paper mache...

RE: Miniature Golf Live Loads

100 LL + 20 DL sounds about right, but no boulders please!

RE: Miniature Golf Live Loads

I too think LL 100 psf, thinking 'exit corridor' sufficient.
but the DL...
unless mom was right that the leprechauns transported the ball from the top of the volcano to the level below and then from the hole at that level to the level below that... there may be a considerable superstructure, considerable as in depth, above your basic slab structure...
but, she was right about the Easter bunny
