shear friction reinforcement
shear friction reinforcement
(OP)
Hello, I am checking the reinforcement at the construction joint of a retaining wall.
Regarding the dowels which will be verified versus the shear friction, is the reinforcement Avf the total steel section of the cross section or the one located at the tension face ?

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.

I would be grateful if u can post it. Thank u.

If moment acts at the section, it is desirable to distribute the shear friction reinforcement at the tension face. Otherwise, distribute it uniformly.

I asked this question because I had a doubt since shear friction will be resisted by the dowels crossing the shear plane.
Therefore, since the section is reinforced from both sides, both reinforced sides will be resisting.

Were those engineers suggesting that shear friction capacity could be used to justify a design where diagonal tension shear checks could not be satisfied? If so, they were horribly mistaken with regard to what shear friction is and is not.
It may be more nuanced than that. The only design guidance that I know of on dowel joints, separate from shear friction conceptually, is this: Link. It turns out that dowel capacities are rather heavily influenced by the anchorage condition of the dowels.

If that is correct, where does shear friction come into it? What shear force are you trying to resist?

I thought he was talking about the joint between the footing and the wall. Thus the discussion of tension vs compression reinforcement contributing.

Do I have the right link? When I open it, I get an abstract for a "fib" bulletin which costs 180 Swiss Francs.
