Minimum Reinforcement in Footings

Minimum Reinforcement in Footings

Minimum Reinforcement in Footings

(OP)
Why is there no apparent code requirement for minimum reinforcemnt in, specifically, continuous wall footings?

Is there a requirement that I do not see?

Please advise - Thank you!

RE: Minimum Reinforcement in Footings

For the US, see ACI 318-02 10.5.4.  This referenced section 7.12.

RE: Minimum Reinforcement in Footings

For a continuous wall footing, in the direction of the wall, ACI 318-02 22.7 allows for unreinforced footings.  The reason is - that it is OK for such a footing to crack.  It will still provide it's structural function, which is to spread the load to the soil.  And no one will see a crack, as it is buried.

RE: Minimum Reinforcement in Footings

in addition to the ACI 318 requirements, some local jurisdictions have a minimum requirement of 2 #5 in the bottom of a strip footing and #5 at 12" o.c. each way in the bottom of a spread footing.  Even if the engineering shows no rebar is required.
