ACI 318-05 Appendix D, Section 4.2.1 has only a brief discussion of using supplementary reinforcing in lieu of the Appendix D methodology. Can somebody suggest some references (preferably including examples) of using supplementary reinforcing for increased shear capacity?
My application is doweling into the edge (the 12" dimension) of an existing reinforced 12" thick slab. With the dowels centered in the slab, there is not enough effective embedment depth to develop enough shear resistance perpendicular to the face of the slab. I'm trying to find a rational procedure for determining the shear capacity of the dowel considering the effects of the existing slab reinforcing.
Would the shear friction provisions of 11.7.4 be applicable? Or does the shear cone make that approach invalid?
Thanks,
David Finley
