A tie would be almost useless at the joint. I believe that the bottom tie location should be based on consistent spacing from the top down. Upvote 0 Downvote May 21, 2016 #4 hokie66 Structural Jul 19, 2006 22,656 The greater the pressure on the footing base, the more likely the...
Your bars are smaller and your area of steel is cut in half by doubling the spacing. You didnt specify if this was for the slab on grade or for footings or foundation walls. If it for a slab on grade for a typical residential garage what you have is probably more than enough. Upvote...
