Diaphram/Collector Connection
Diaphram/Collector Connection
(OP)
What is the proper way to get the force from a roof diaphram fastened to truss down to a masonry shear wall. I know there are several options, but here's the part I'm interested in....The truss is an atic truss. So the distance from the diaphram to the top plate is 2'. Thanks.

Can you give a more thorough description of the truss construction around the bearing wall? If we have a clear picture of what you're talking about, you might get more meaningful advice.

For shorter heels I've used a thin bent plate. Maybe you can do it by extending the CMU wall up the 24".

I have a 12" reinfored CMU wall coming up to a top plate (the top plate will be used as a nailer, at the contractors request, rather than usiing masonry/wood tie downs) The truss is 24" tall at the point it meets the bearing wall. The 24 " is from the topplate to the sheathing. The trusses are 2' o.c.
I was trying to eliminate the need for the contrator to have to construct a mini shearwall between the trusses. I think what I'm going to do is run sheathing along the end of the truss (so the sheathing will be be vert oreinted) and nail to the end of the trusses, to the top plate along the bottom, and 2x4 blocking along the top between the trusses. The roof sheathing will be nailed to the 2x4 blocking at the top.
Thanks everyone for the input.
