Framing & StructuralQuestion 443 of 700
For a wood structural panel shear wall to develop its rated capacity, how must the panel edges be treated where sheets meet?
a.Edges may be left unsupported as long as the field is nailed
b.Only the top and bottom edges need backing
c.All panel edges must be backed by framing or blocking and nailed
d.Panels should be gapped and left unfastened at vertical joints
Explanation
Shear is transferred through fastened panel edges, so every panel edge must bear on framing or blocking and be nailed at the required spacing. Leaving vertical edges unsupported or unfastened, or backing only top and bottom, breaks the load path and drastically reduces the wall's shear capacity.
