I doubt that shear loading will be an issue for the house I'm planning - a small, 20 x 20 x 2-story home. I'm inclined to think that a wall system wrapped in sheathing will be adequate resistance to shear.
What is the most common way to support SIP's on a timber frame? I've seen examples where the posts are supported inside the foundation walls (going all the way to footings in the basement in some cases) with the SIP's resting on sills atop the foundation walls. At first glance that seems a bit unnecessary. Just curious at this point as to what the "best practices" are.
