Spalled bridge concrete pedestal
Spalled bridge concrete pedestal
(OP)
I came across a highway bridge (concrete deck over steel stringers) where the stringers rest on concrete pedestals over concrete piers. Two of the concrete pedestals have spalled from the anchor bolt line (one anchor bolt on each side) undermining the masonry plate by about 15%. The curious thing is that the reinforcement that is exposed consists of a lonely horizontal rebar at mid height. Wasn't it supposed to have more reinforcement than that? I have been looking for sources on bridge concrete pedestal design but have not been lucky. Can I have some help on this? Thanks.

Anyway, I've seen worse, much worse. If the concrete is sound, just notify the owner. I wouldn't lose sleep over it.
