Plywood Diaphragm Connection at Roof Ridge

Plywood Diaphragm Connection at Roof Ridge

Plywood Diaphragm Connection at Roof Ridge

With a lateral load acting perpendicular to the roof ridge your horizontal diaphragm shear is maximum. Conveniently at the same time the diaphragm is discontinuous. What are people normally specifying to get the load trough this joint?

RE: Plywood Diaphragm Connection at Roof Ridge

Assuming your roof is not taking a ridiculous amount of lateral load then shouldn't blocking between the roof trusses be enough as long as the nail spacing and penetration requirements are meant.

RE: Plywood Diaphragm Connection at Roof Ridge

The problem comes in here when ridge venting is required, but there is a doable detail for even that with blocking and nailing.

If there is no ridge vent, just provide blocking at the ridge between the trusses and nail the sheathing to it. No worries.
