Is it at the end of the foundation or at the corner of the shear wall where it meets the foundation? Also, is the depth of the shear wall accounted for in the DL? I still don't get to the factor of 4.2.

Your help is very much appreciated.

Thanks!

Mike has a topic on pivot point. If you go back to this question in his notes, he directs you to it. Essentially, the pivot point is the point about which the whole item would turn.

Example: A pinwheel has a center pivot point. If you blow on it, the pinwheel will rotate about it's center pivot point. If you push on a wall from the left, it will rotate clockwise about the pivot point
