Cantilever Swimming Pool Problem
Cantilever Swimming Pool Problem
(OP)
Dear All,
I have some enquiries regarding the design for RC swimming pool.
The situation is like this: The piles were piled as per the proposed swimming pool at the earlier construction stage. However, now the client/architect has changed the layout of the swimming pool. As a results, the swimming pool wall does not directly sit on the existing piles; making some of the portions of the swimming pool to be cantilevered. We proposed to add more piles to the cantilevered one (roughly 2.5m cantilever). However, due to budget constraint they did not allow to add more piles.
My question is, how to analyse the cantilever wall?
If piling is out of the solutions, then for me to support the RC wall, is only by using beams, correct?
Attached is the cross-section for the swimming pool for your reference.
Thanks for your input and help.

Recommend you urge the owner to invest in the piles and save a lot of headaches in the future.

Vertically cantilevered wall behaves per original design. Horizontally cantilevered beam/slab should get analyzed for the endpoint moment from the wall's lateral pressure plus the vertical load of the water weight. Rebar lap detailing is important.
Consider calling a screw pile guy if the owner is balking at the re-mobilization cost to add timber (I'm assuming they're timber) piles. Screw piles or push piers are likely the retrofit in 5 years anyway.

There may be some potential so long as it can be a cantilevered wall rather than a cantilevered slab. If you share a plan drawing, we'll be happy to weigh in. In fact, you'd have a hard time preventing it.
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.

Thanks for sharing your opinions. Attached is the layout plan,
Yeah, it surely looks like I need to extend the slab to catch the piles there.
Cantilevered wall? Do we analyse it like a deep beam method?
Yeah, we are still trying to convince them to add more piles.
Oh, noted on these.
I totally agree with your comment.
