FW: Atypical Shear Friction

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I agree - without the two hard surfaces interlocking, I don't see how
tension will be developed in the rebar spanning the gap, at least from the
traditional POV regarding shear friction.  It would seem that dowel action
on the part of the bars would be the only mechanism that would manifest,
given the description of the setup.

FWIW,

Todd,

That sounds like a condition in which no significant shear friction can be
developed.  I would look for a way of developing shear transfer by another
mechanism such as mechanical interlock, such a suing the dowels in shear and
bending.
