Hello All,
New to this forum, but I have a question about the clear spacing between bars. For the purposes of calculating development length, ACI318-11 12.2.2 allows you to use the reduced value if the clear spacing between bars is at least twice the bar diameter. Does this spacing restriction apply in the vertical direction between layers as well as in the horizontal direction?
It seems like it would based on the language of the commentary and table, but the commentary makes specific reference to 7.6.1 (the section on horizontal clear spacing) without mentioning 7.6.2 (the section on vertical spacing). Thanks.
Jeff
