It is a shear wall (not sheer).

A shear wall is a structural wall designed to resist lateral loads along the wall. These loads are typically wind or earthquake loads. Shear walls may or may not be load-bearing.

Here is a non-technical example.

Take a 30 foot by 50 foot building, no interior walls. The wind blows against the 50 foot walls and blows it in.

Now, build a shear wall perpendicular to, and against, the center of that 50 foot wall, effectively creating two 25 foot walls with a 'T' wall in the center. The same wind blows against that 50 foot wall and the shear wall in the center holds the wall up.

It's "shear" wall, BTW, a "sheer" wall is one is vertical or nearly so.

Why are all of Dan's posts edited so that we can not see the original question? Am I missing something here?
