How to calculate shearwall requirments on a set of blueprints? I have plans for a raised ranch I changed and cut 3 feet out of the width. So the walls have slightly changed, not 100% sure how to calculate the new requirements.

I'm pretty sure I'm going to have to use steel in the front of it, but I'm going to be close in the rear. Might get away with just plywooding the rear wall.
