corner r/f in concrete wall 3

[Structures33]

Which of the two (A or B) is the correct way to detail the interior horizontal bars of a concrete corner/ intersection? Assume that the walls are exposed to lateral on both sides.

I've uploaded a pdf -- CORNER_RF.pdf

Thanks

I was responding to Mike, who compared Type "A" to the hairpin detail. If I understood Mike correctly, he said that there would be four stacks of rebar at some locations using the hairpin detail. I only see three stacks (at the diagonal), same as detail "A". Overall, Type "A" and "B" both seem to have busier reinforcing in the corner than the hairpin style.

Right, we agree. I thought you were comparing the two original details. The perils of not reading straight down the page.

YS,

I can see your point in seismic detailing. Although I have a lot of years experience, little of it is in seismic applications. But regardless of the corner bar, I would think hairpins would be preferable to end hooks or cogs in any form. Remember, we are talking about walls, not column to beam joints.

*shakes head* I've done so little in-situ cast work since leaving Canada, I automatically thought of beams and columns, despite the fact that the word "wall" must appear twenty times in this thread!

*sigh* Must be Sunday; My appologies all!

Cheers,

YS

I have used diagonals on large heavy walls where the efficiency of the joint (ie moment transfer) was critical. In this case, I would include a fillet (triangular piece of concrete on the inside face to reinforce the corner).
