concrete dowels in shear with smooth slip plane
concrete dowels in shear with smooth slip plane
(OP)
Is it feasible to design a doweled connection between new and existing concrete, that is carrying shear, where the plane between the two placements is very smooth? I have an existing condition that is creating this issue. Shear friction concept would not apply since there is little or no amplitude in the face of the older concrete. I also do not want to roughen it for several reasons. In this case is it reasonable to rely just on shear resistance of the dowel steel, assuming that the dowel is embedded sufficiently? ACI 318 does not appear to mention this concept. Any one ever done this? Shear forces are not large, 1 to 2 kips of factored shear per dowel.

Of course I would prefer like hokie some sound support, but there are bunchs of people out there promoting for the most variegated reasons that we sometimes proceed otherwise; in any case his observation is very well brought because it is too much a frequent cause of failure any kind of lack of bearing at supports.
