ACI 318 Tie Requirement
ACI 318 Tie Requirement
(OP)
7.10.5.3 in ACI 318 states that "Ties shall be arranged such that every corner and alternate longitudinal bar shall have lateral support provided by the corner of a tie..." I am designing a 24" square column with 4 - #8's on each face. These bars are less than 6" from each other, so no ties would be required for that provision. However, since I have an even number of bar on each face, "every other bar" is different depending on if I measure from the right side or left side of the column face. My question is, would I need to enclose the two interior bars on each face with a tie, even though they are adjacent within 6" to a tie corner? See attached detail. Thanks.

If OP is concerned, you can have alternate cross tie locations, i.e. provide one on the left and the bottom set of face reinforcements and then provide one on the right and the top set of face reinforcements the next.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
