Pipeline Support Piles
Pipeline Support Piles
(OP)
Out here in California petroleum, we typically use 'T' supports with cast in place concrete "pile" foundations. Some supports have lateral forces but many are only providing vertical support. Right now there is a school of thought that all of the supports should have rebar cages in the foundations. I used to be of this school of thought because of temperature shrinkage control comments in the ACI 318. However I just came across a portion of the Plain Concrete section of the ACI that states that cast in place concrete piles are not really covered in the ACI. Additionally, read an old post by GeoPaveTraffic that mentioned rebar cages aren't really necessary for supports only under compression. Regardless, for a support like this, with little (friction) to no lateral forces, I'm not really seeing the need for the rebar cages. Has anyone run into this debate in the past? Are there any codes or standards one would point to? Also if the friction is an issue, couldn't something be places between the pipe and support to limit the lateral friction?
Thanks in advance :)
Thanks in advance :)





RE: Pipeline Support Piles
You'd be far better off to include at least minimum temperature and shrinkage steel. What's that going to cost you, except a possible bad reputation if you don't. I wouldn't want to be known as the engineer that wouldn't put a few #4 in a column in earthquake territory!

Thanks again
RE: Pipeline Support Piles
Drop the pipe support element nearly to the bottom of the concrete and then you could probably forget about the vertical bars.
