Sign Post Foundation Design ?
Sign Post Foundation Design ?
(OP)
I am looking for some sign post foundation resources. I would like to understand how to approach the process.
I am reasonably familiar with pad and pier foundations for steel buildings, but have been given some display signpost foundations to support a half ring of signs around the front of a car dealership. I am not looking to replace the structural designers who have produced the work, but I would like to understand the process.
We are looking at 2 kip to 3 kips axial dead Loads for the structure at each sign post and approximately 3 kips horizontal wind load with about a 750 in-kips moment at the bottom of the post. Post are HSS 8" x 8" x 0.5" thick square post approximately 18'-6" tall. They are bolted to a 6" x 6' x 9' deep reinforced concrete pier with 1 1/2" x 48" anchor bolts (6).
Again I am not looking to redesign these sign post, I just want to understand how they developed the numbers.

ps. I am also familiar with flag pole foundations, but these are not quite the same.

Check the dimensions, 6 No. 1 1/2" bolts but only 6" wide? Is the moment uni-directional?
Michael.
Timing has a lot to do with the outcome of a rain dance.

Sorry I just read you comment and then re-read my question. The main pier for the sign is 6 Feet x 6 Feet x 9 Feet deep. Sorry about the inch marks, I never saw them when i proof read the question.
I hope this makes it clearer.

They give you a limit on when the equations are no longer applicable (i.e. the foundation is too flexible)

Ron, do you have specific DOT's which might have Design Standards for pier foundations. I have looked at Illinois and Florida DOT sites and found volumes of info. It will take a while to review some of it and learn how they specify standard sign post pier foundations.
Again thank you for comments and help.
