Gas station Canopy Footing
Gas station Canopy Footing
(OP)
Hi,
The gas station canopy is 102'x30' and supported by 4 HSS columns. I am designing only the footing and making sure it is sized for a moment as well as axial load provided by canopy manufacturer. Below the canopy is a slab on grade. The bottom of each of the four footings will be 4'-0" below the finished grade. There is also a slab on grade for cars and trucks to drive up to fill up. Do I need to take into consideration any impact for loads from these vehicles onto my column footings?

Any impact load from a vehicle actually running into the column is usually not a problem as curved bollards are usually installed around the gas pumps and columns.

Sorry if I am stating the obvious.

Better than hitting the gas pump!!!

Oh, and Dave, I think I found a picture of your daughter's run-in with the pumps.

Not funny for the owner of the SUV, of course.

It really isn't that stringent. I don't have the IBC in front of me, but it's something like 2 or 3 kips at 2'-3' above finished grade.
This loading is intended to account for a vehicle accidentally backing into it. And this is certainly a possibility.
Now, if you have the bollards as others have suggested, then you wouldn't need to design for the impact, as the bollards would absorb this.

Again, I am probably just stating the obvious.

traffic surcharge to check for downward pressure - check
Thanks so much for all your input.
love this forum.

I guess it's just a check I've been accustomed to do whenever I have anything exposed to vehicular impact.. but I think you're right.. In this particular case, it's quite obvious by observation that wind loading would control both overturning moment and probably shear on the footing..
So on second thought, I change my answer to "No."
