Design method for Pipe Bolted Moment Splice with Internal bolts

[kiskertlugas]

Hi All,

I'm looking for a design method for a Monopole Pipe Bolted Moment Splice with Internal bolts.

See attached picture too.

I've found reference for Petersen, but I wonder if there's any other method, ar least this Petersen method is available somewhere? (It seems hard to obtain the original paper.)

Thanks in advance.

Seems to me that the methods used for external bolts would still apply with just a slight modification to the lever arm. The bolt tension will still be dominated by prying action.

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.

I think I've seen similar construction on wind generator towers, I wonder if there is any publicly-available information on them?

You will have to use the Slip Critical rules for surface prep and primer/paint coatings. Thus why a bolted Moment is so rare when welding is an option.

Not sure slip critical surface prep is required for these, but pre tensionned bolts certainly are.

It's just a regular flange bolted analysis which will include any prying action. Nothing really special. We've used these kind of flanges on all of our tapered flag poles. I think that Shigley has some comments.
