Default Shear strength of screws

And put on earth quake straps on the foundation and sil board.
That will work in other cases of strong wind. A force trying to
flatten a house.

Another thing we did in earth quake country was to put in shear walls.
Often the outer boards are 1x tongue and grove but they silip and slide
in wind. On the inside put sheet ply It doesn't have to be all walls,
but some of the side on all sides. Keep that side from laying over.

Used to be that framing had to be toe nailed...
Now I see nails used from top and bottom sil to studs. Not as strong.
The toe nailing really locks it in from both sides.
straight nailing will not withstand storm forces as much.
But then again, most roofs will easily lift before the framing gives.



Typically hurricane straps add tremendous strength if you are building
for wind storm resistance.
