anchor bolts in drilled piers
why is there no allowance for the shearing of ties in the concrete breakout strength, in app. d? if you have a pier or pedastal with shear ties, don't the ties have to shear first before the concrete breaks out.

the analysis of most of appendix d assumes concrete only, reinforcement can be used if the concrete fails. see d.6.2.9.
in aci 05 it only goes to d.6.2.7
