Does anyone have any reinforced concrete design examples for a light pole pedestal that will be located on a bridge? Maybe a good AASHTO or ACI reference design example?
I am trying to design a pedestrian bridge which has a 6" thick concrete deck on prestressed concrete beams. The bridge deck will be 11.5' wide out-to-out, with 10' of clear width between the steel pedestrian picket railings. The 2 beams will be spaced at 6'. The light pole pedestal will be located behind the steel pedestrian picket railing. The light pole pedestal dimensions will be approximately 2.5' wide by 5' long, and 6" thick to match the bridge deck thickness (kind of like a "blister" on the side of the bridge deck). The light pole itself will be about 21' to 25' feet tall (probably one of those decorative aluminum ones). Since the thickness of the concrete pedestal is limited to 6" (to match the deck thickness), I'm sure the pole will need to be thru-bolted.
I know there will be axial dead load, wind load moments (about transverse and longitudinal axes), dead load moment about longitudinal axis, shear, and torsion about the pole axis to consider.
Thanks for any tips or leads!
