Illustration showing the methods for reinforcing the continuous load path from upper to lower walls. The shear wall is pointed out, in addition to the specific nail pattern and the anchorage at corners

Strengthening the connection between levels can also be accomplished by using properly nailed structural plywood sheathing in specific wall sections. These sections of wall are referred to as shear walls.

Shear walls must use structural sheathing, must be properly nailed in specific patterns, and must be anchored at the corners
Shear wall size is specified by building code

Metal straps may also be used to connect the levels of a structure. These straps must be nailed to the studs and not just the sheathing.
