Elevated Swimming Pool

[drago8]

Dear All,

I wish to seek for your advises and guides on designing the above-mentioned subject. The main project is to construct shoopping complex plus apartments.

Instead of inground, the swimming pool will be build on the third floor of the building. I have yet to find a structural guide on how to design the elevated swimming pool. Could anyone share a link if they have about this subject? What factors shall I have to take a great care of? I believe check for crack width is important and deflection of the slabs?

Thanks for your help in advanced.

1) The main thing, in my experience, is sorting out all of the complexity surrounding drainage, topping, coatings, and equipment. All of that stuff can impact slab folds and beam/column layout significantly.
2) Obviously, you've got that rather large seismic sloshing mass to consider. And perhaps a mass discontinuity.
3) Issues surrounding water-tightness as you've mentioned.

It's nice if you've got a pool consultant on board to help out.

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.

I imagine ACI 350 is applicable here (assuming concrete construction), though this obviously isn't truly an environmental structure water-tightness is clearly going to be the biggest serviceability issue.

Aren't most elevated concrete pool structures poured within a continuous metal (stainless?) bottom and wall form, to provide a leak-resistant "tub"?

I would apply the same principles used in elevated tank design. You will probably need to take a look at the sloshing effect due to seismic loads, secondary moments due to drift or P-delta effect, load combinations with the pool empty and filled, etc.....just a few brainstorming ideas

Seismic is usually an issue, but don't forget the obvious: the big fat guy belly flop, which creates a strong pressure wave (infinite half space). You would think that there are closed form solutions for this, but I never found a simplified analytical model, so I relied on my PhD friend for that lateral load (in addition to hydrostatic).
Stainless (316, not 304) is the way to go, especially for an existing building. No leaks after 50 years.
