RE: Wood truss as drag strut

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Just run the plywood all the way up the wall and up the side of the truss and detail the nailing at the roof for the shear transfer.  Call out the shear wall nailing pattern to be done at the side of the gable truss also.  Then the gable truss isn’t doing any of the shear transfer.  You should detail the nailing from the plywood to the wall top plate also.

I guess I was not clear on the wall and truss orientation.  The trusses are gable trusses so they span perpendicular to the ridge.  The shear wall is parallel to the truss.  I either use the truss as a drag strut, or take the wall to the roof at the wall only.  The trusses would be adjacent to the wall. 


I don’t see how the slide clips would help.


It seems to me it would be a cleaner detail to take the wall to the roof so I don’t have to have a transfer of forces from the truss to the wall.  I also don’t have to concern myself with the truss supplier designing the trusses correctly.

A slotted fastener from drag truss to wall is advised (Simpson DTC or STC clips).
