Hi all, In ACI 3018 11.5.5.1, there's a minimum spacing stipulation of d/2 for perpendicular stirrups. This usually has not been a problem for me, but on my current project, I have a little cantilevered sidewalk on h=12" t-beams, making my d value only about 9". Stirrups spaced at 4.5" seems a bit excessive to me. cdc free rapid testing
