Splice bottom reinforcement at slab's midspan

Splice bottom reinforcement at slab's midspan

(OP)
Hi everybody .
I just want to know if it is allowed to splice the tension bars of the slab's bottom reinforcement at the slab's mid span ? ( Based on ACI )
Thank you  

RE: Splice bottom reinforcement at slab's midspan

ACI-315:99 Sect 2.7.2 "In beams and girders, splices should preferably be made where the stress in the bar is minimum, that is, at the point of inflection. Splices where the critical design stress is tensile should be avoided by the A/E wherever possible."

It is not saying that it is not allowed but it is not advisable, if you can move the location of the splice so it is not in the highly stress tensile region than I would do so. Otherwise, I would increase the splice length to 1.3*bar_development_length and make sure an inspection is made to ensure contact splices have been provided.

It wouldn't be considered good detailing.

I agree with asixth.

RE: Splice bottom reinforcement at slab's midspan

Clause 12.15 of ACI318-08 cover this.

And it looks like asixth can read!
