Drag force/Shear wall connection

Drag force/Shear wall connection

Drag force/Shear wall connection

(OP)
Hi Folks:

Whats the best way to transfer the shear, when shear wall running parallel to wall?

1. extending wall ( build pony wall) all way up to floor/roof?
2. provide floor truss on top of wall?
3. Rim joist on top of wall?

If we use truss, sheathing is not necessary to bring all way up to floor, I guess. Then we need to provide drag load to the truss manufacturer. Sometimes that load could be huge for high wind area.

I am curious which way is the most common practice or cheaper construction.

Please advise.

Thanks in advance

RE: Drag force/Shear wall connection

I think a rim joist would be the least expensive and most common way to transfer a lateral force from a diaphragm to the shear wall below. You could also use a drag truss, as you mentioned.

I think most builders would not like to build a pony wall.

Blocking between trusses - allows for more flexibility. Good for low loads

Drag truss over the wall for higher loads
