Steel Post in Concrete Footing Uplift Resistance

[reverbz]

Hey Guys,

I'm doing a shade canopy with steel posts embed into concrete footings. The uplift loads aren't high(600 lbs or so per post) but I'd like to know if the column can resist it or will it be pulled out of the footing? I know you can weld a baseplate on the bottom of drill rebar through the post but just wondering do you really think that's necessary with this load? Is there some way I can prove it's OK without that?

Thank you!

There’s been a few threads on it. 600lbs will be fine.

Steel Column to Concrete Bond Strength? - Structural engineering general discussion

I have a 1.25" sched 40 pipe embedded into the ground 6'-0" and a 12" diameter concrete collar poured around it at the surface (12" deep)... I'm trying to figure out what the bond strength is between the steel pipe and the concrete for vertical force resistance. My concern is that the...

does anybody know what the ratio of bonding stress between embedded steel plate and concrete? is it the same as reinforcement?

Anchor the pipe in the footing. The cost is minimal.

Bond between smooth pipe and concrete is not reliable. Reinforcement is deformed, providing good bond with concrete.
