embedment for pile cap

embedment for pile cap

(OP)
Using helical piles, the embedment in a pile cap is 8 inches. The Pilecap total depth is 2 feet. What is you guys opinion/thoughts on the amount of helical pile embedment on this?

RE: embedment for pile cap

Playswow,

I little advice that will take you a long ways after your school career ends. If you bring a question to the table, bring your best answer as a starting point. This does a few things:

1. it tells everyone that you are not trying to get people to do your homework
2. it might just solve your problem
3. it shows your piers and future bosses that you are approaching your job with zeal. This will take you a long ways.

RE: embedment for pile cap

Using the CRSI tables I would increase the total pile cap depth by at least 2" as CRSI uses a 6" embedment of the pile if I remember correctly. I would also use the CRSI pile cap depth as a starter.

What? Why would you assume that from this question? I'm out of school but yes, I am a EIT with about a year of experience.

Thanks man I will locate and use that resource.

RE: embedment for pile cap

In my area, helical piles will be installed long and then be cut down to the appropriate elevation before installing the cap plates. As such, vertical control isn't too bad. I'd say that you could embed the pile as little as 2" and be reasonably sure that, at the end of the day, there won't be air space between the underside of your pile cap and the top of the pile. It very much depends on the detail that you're using however.

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 KootK,
Pile Cap Dim = 200 sq ft
Some vessels are approximately 250 to 500 kips, so you can see why I asked ha
