Opening Near End Of Shear Wall
Opening Near End Of Shear Wall
(OP)
Hey all,
What is the best way to handle a short wall segment at the end of a shear wall that does not meet aspect ratio requirments? I feel that in the attached example, two options are present:
1) Ignore the 1.5' wall segment and window and design the remaing wall as a perforated shear wall.
2) Use the two wall segments on either side of the door to design the wall as segmented. If it is segmented, what transfers the lateral load across the window opening to the first segment? Top chord? Header?
If either of these two options are viable, would it be best to still place a hold down at the outside of the 1.5' segment or are they only necessary on the segments of wall designated as shear carrying segments?
Thanks much!

I would place boundary nailing from the top portion of the wall to the top plate. The top plate would be designed as a collector to distrubtute forces to the shear wall segments. This means that you would need to have to stagger the members or use something like a Simpson CS strap (or larger if the forces require) to ensure continuity.

With that said, I think that (1) row of boundary nailing at the top plate and (1) row of boundary nailing at the top of the gable end would be required.
Keep in mind, that the boundary nailing at the top of the gable will be less than that of the shear wall segments due to it being continuos.

I wouldn't check relative regidity.

From your diagram, it appears that one wall is 7-1/2' and the other wall is 6' in length. So should the loads be distributed to the walls by proportionally (55% and 45%).
There is an example in the seismic design handbook.
