The only difficulty is that you don't have a ton of information as to
how
well SIP panel screws or panel spikes (big nails) will deal with the
seismic diaphragm loads in a "desireable" way (i.e. ductile response
similar to nails through structural sheathing in typical diaphragms).

-----/Original Message/-----

Are "big nails" (officially known as "spikes") of any great benefit for
seismic (or wind) resistance?

I would think that tearing of the panel would control, and that "lots of
small" would be preferable to "a few large" fasteners.

Sorry, it's been a LONG time since I looked at any of this.
