Reinforcing Dowel Placed In Fresh Concrete
Reinforcing Dowel Placed In Fresh Concrete
(OP)
Hi All,
I have a situation where the contractor installed reinforcing dowels after the concrete was placed in the wall, rather than installing the dowel and placing concrete afterwards.
I cannot find information regarding this situation - whether the codes allow this, and if so what would the calculated tension capacity be? It would seem to me it would be less than if cast in.
Thanks for any information to shed light on this.
Regards,
Beamman

As far as determining that capacity, I haven't seen any number put to it. I would think you could lose a fair amount of bonded length, so it could just be a reduction in Ld or Hef for calc purposes. Tough to put a number to though.

It probably did not settle/get pushed all the way down thorough the slab to the very bottom where it will be exposed to corrosion from below, but was it evenly depressed so it is at the right depth all the way on its length?
A bar placed before the concrete is poured has to be suspended "up" from the form, but here, what held it up so it didn't droop too far down in places, but was too shallow in other places?
