Unreinforced Pedestals?
Unreinforced Pedestals?
(OP)
Two questions,
Would a pedestal with an aspect ratio of 0.5 and headed anchors that extend all the way to the bottom mat of the footing be considered unreinforced or could the anchors bolts be considered the longitudinal reinforcing?
Also, if the anchor bolts are failing for concrete breakout can shear friction between the pedestal and the steel base plate be considered in order to alleviate some of the load being applied to the bolts?
Thanks,

RE: Unreinforced Pedestals?
How exactly would you evaluate the friction between the surfaces of a baseplate and concrete or grout with an indeterminate coefficient of friction? What is the nature of the failure, i.e., if the anchors are acting together (tied together by the baseplate) is the pedestal too narrow/small for the horizontal forces?

Good point about the earthquake loads. So would you agree then that this can be used to alleviate the horizontal thrust to the anchor bolts from DL+SL? (this is a rigid frame)
One other question. With this shallow unreinforced pedestal, would the anchor bolts be an acceptable form of reinforcement for shear friction between the pedestal and the footing if they had not been poured monolithically?
I would think they would serve the purpose of preventing the two pieces from separating as they slid across each other.

What are the pier dimensions? Loads?
