Swimming pool design
(OP)
Dears,
i am designing a 40x25m swimming pool on ground.
1. Do i have to create any kind of joint in it (40m) ?
2. Do i have to apply thermal gradient effect
3. What are the approximate dimensions of the raft and walls from your experience for such pool knowing that water height is 80cm
Thanks alot

RE: Swimming pool design
2. Yes.
3. Not applicable - We would need a great deal more information to be able to help you with this level of detail.
Have you done any pools in the past? They are not as trivial as they seem!
RE: Swimming pool design
i have made cyclors and treatment stations tanks design, in which i considered thermal gradient effect with no joint at all. however, i was wondering if i have to make the same for a ground pool.
i am planning to model it on SAP, as a raft and wall with all the possible combinations of load and check the typical checks such as soil capacity, settlement, bending and shear.
is there any other considerations?
and what is the minimum dimension of pool to neglect the joint ?
RE: Swimming pool design
2mm (BS code)

You still haven't told us about the service environment...
RE: Swimming pool design
the site is in a mid-area between sea and mountain (average Mediterranean weather) but as you said, the soil is clayey expansive one for which we will do some treatment (strong compaction and base course fill underneath rafts).
Any advice?

can you please explain that more?

My only issue is the length of the pool (40m)and if i need to make a joint or thermal consideration

its of course 0.2mm not 2mm (sorry for the spelling!)
RE: Swimming pool design
BUGGAR's method is a clever one. You need to be careful that the intermediate units are not too large though as pouring intermediate units provide a lot more thermal restraint than just doing sections piecemeal. Contractors in the UK love this method for obvious reasons, but for heavy duty stuff is a lot more expensive for reinforcement.
Maybe I'm being ignorant but why do you need a SAP analysis? You can size the wall on the back of a post it note using M = (1/6)(k0)(y)(D^3) and do a simple drained/undrained SGBP and settlement calc. Deflection might be an issue if the internal faces of the walls are going to be clad with tiles or similar as these will obviously be more brittle than the walls.
Good luck! PS Don't think the client would be too impressed with a 2mm crack ;)

"the site is in a mid-area between sea and mountain (average Mediterranean weather) but as you said, the soil is clayey expansive one for which we will do some treatment (strong compaction and base course fill underneath rafts)".
This tells me you REALLY need the advice of an experienced geotechnical engineer. Compacting expansive soil is probably the worst thing you can do where water later may be leaking to "feed" that expansive soil. This likely will be the downfall of this job if you follow through with that statement. The resulting picture won't be pretty.
