Irv:

If you using a HD or a PHD at the wall ends, you need to also account for the fact that you will be drilling through the supporting beam. Depending on the size of the anchor bolt, the reducation in section properties can be quite dramatic. Moreover, the maximum moment will usually be at this location.

the holdown force is multiplied by the omega factor (2.8) on the beam
supporting the shearwall. Also in CBC country you use the special seismic equations
and the standard equatios to design this beam.
