Hi All RC structural engineers !!
i need pour help to solve the issue (non conformity of rebar splicing= bended rebar ( see photo in thé attachement = 12mm diamètre bar in the neutral axis ).

Column rebar non conformity )!

What do you think if use epoxy mortar
To repair the mechanical discontinuity of the Bad splicing of the bar

Can thé bar support the stress of both compression and tension ?? If yes then thé issue is closed . If not thé what solution ??

Thanks All

Salut.

Where is the mechanical discontinuity though? I don't see it. Is this a high seismic application or something more normal?

Can't see how the bar is spliced. Draw a picture. I assume that the buried portion of the bar is vertical, otherwise all bets are off.

It seems pretty clear that the bar in question is incapable of transferring the full bar force to the already cast-in-placed concrete, whether the force is tension or compression. The problem belongs to the contractor and he should come up with a proposal.

Perhaps the full strength of the bar is not needed. If that is the case, the EOR should decide whether or not anything further needs to be done by way of remedial measures.

It appears that, to develop the full strength of the bar, some welding would be necessary, which would engage the buried portion of the bar and the upright portion. I see no other solution.
