Transmission Pole Foundations
Transmission Pole Foundations
(OP)
I am a structural engineer that is getting into transmission line design. I'm working with a couple of experienced designers who have been doing this for 20 years. When it comes to the design of a concrete foundations, what code covers this? Are there sections in the NESC about it? I haven't really got into it yet and was curious.

If you use PLS-CADD like about 90% of the people that do line design, there is a Caisson program that is included in the package. The Geotech guy sits in the next cube over and I think he uses an EPRI sponsored program called FAD or MFAD and I hear the name L-Pile thrown around. We used to use a program called Beamcol in the old days to design drilled piers.
My take on it is you need good soil data no matter what program you use.

I am no foundation person, but I would treat the drilled piers as a beam column and look into ACI 318 to design the reinforcing. You might also look at EPRI and see what reference material is available. They have a MFAD program available to EPRI members for single pole foundations and an HFAD program for H-Frame structures.
