Horn Formula A

[Strengi]

We are currently in the process of analyzing a steel base plate for a telecommunications monopole, and have stumbled across a reference to Horn Formula A. Does anyone have any information they could provide on this? If so, it would be more than appreciated.

Do a Google search on "horn formula", it gets a number of direct hits right off the bat.

Thanks for the info, but trust me, I already tried that route. If it would have worked I wouldn't have been here The results from that google search return information on a horn formula that doesn't apply to base plate stresses, but only to some mathematical formulas. Again, thanks for your reply, though.

Sorry. Not having the reference which you have, I had no way of knowing if the formula in question was specifically a base plate formula or something more general. Maybe that's why the "A" is there.

What's the reference?

Unfortunately, the only reference is the mention of using Horn Formula A. I wish we were provided with more information, but we're stuck.

It says use Horn Formula A for what exactly? What document is this written in? (Ya just never know what might trigger someone's mind.)

Okay, doing some detective work on my lunch hour here...

There is a standard, ANSI/TIA/EIA-222, “Structural Standards for Steel Antenna Towers and Antenna Support Structures.” It apparently includes base plates. I've never seen it, maybe that's what you're reading in. Or maybe it contains the elusive formula!

It is maintained by the TR-14.7 Committee of the TIA (TIA- Telecommunications Industry Association, tiaonline.org).

Mr. Dan Horn, deceased, was apparently a member of that committee. He was President of C-concepts, Inc.

One of the items listed on their website is the 192-page user manual for a tower design program, the user manual being written by Dan Horn.

I still don't see a "Horn Formula" in all this, but maybe that'll get you closer. Good luck.

If this was IN some of Dan Horn's stuff, he might have just called it "Formula A", not "Horn Formula A".

I can't thank you enough - I appreciate the information!
