ACI Shear Anchorage Question
ACI Shear Anchorage Question
(OP)
I have an application where I need to use a shear key on a base-plate to transfer the shear from a steel column to a mat foundation. Uplift = 91 kips, shear = 33.6 kips. I have used the AISC Design guide in the past but I was told to check out the ACI anchorage section as they have a design procedure for a shear key. I was looking at my ACI-02 and I guess I am blind because I can't seem to see it in there. Does anyone know where this procedure is, or maybe if its in the ACI-05 and not the 02? Thanks for your help.

ACI 349-01 section B.11.2 describes breifly how to design for a shear lug bearing toward a free edge.
The design shear strength is 4 phi sqrt f'c acting upon the projected effective area. Phi=0.85
The old ACI 349-85 explains the method more clearly as it similar to the the old method of determining anchor bolt pullout. The reprint is still available from ACI for about $15.00, however the anchor bolt design method has been replaced by the CCD method described in Appendix D of ACI 318-02
The old method is also explained fairly clearly in AISC desing guide #7 and is available as a free download for AISC members.
