Af pa sdpws shall be met and wood structural panel diaphragms are permitted to resist horizontal forces using the allowable shear capacities set forth in table 2306 2 1 1 or 2306 2 1 2.
Fastening of the chord or chord enhancement should not inhibit this slip.
The allowable shear capacities in tables 2306 2 1 1 and 2306 2 1 2 are permitted to be increased 40 percent for wind design.
Drag strut at the edge of the diaphragm it distributed the shear force from one diaphragm to another e g.
The diaphragm resists the in plane loads by acting as a large horizontal beam spanning between the supporting end walls that are known as shear walls.
The term diaphragm is usually applied to roofs and floors.
They are comprised of interconnected units attached to supporting members such that the entire assembly possesses both in plane shear strength and stiffness.
As a wood sheathed diaphragm is loaded slip will occur between the perimeter framing member and the sheathing.
This is the most common situation.
Shear diaphragms are essentially planar structural systems found in roofs floors and walls of buildings.

A diaphragm is a flat structural unit acting like a deep thin beam.
A diaphragm structure results when a series of such vertical and horizontal diaphragms are properly tied together to form a structural unit.
A shear wall however is a vertical cantilevered diaphragm.
This horizontal element is known as the diaphragm.
Shear nailing of the roof diaphragm north south the diaphragm loaded in the north south direction has been selected to illustrate the design of a wood structural panel roof diaphragm.
The term diaphragm is usually applied to roofs and floors.
The new or enhanced chord member must be anchored into the diaphragm for unit shear transfer.
These construction systems can be used when designing a building for lateral loads such as those generated by wind or earthquakes.
Anchorage for shear transfer is also discussed in section 22 2 3.
The major components of a diaphragm include the individual deck panels the structural members to which they are connected and the connecting devices or fasteners.
