Plywood diaphragm shear capacity
Webcapacity per bolt = 1/2” dia. × 1.5” × 1600 psi = 1200 lb. The APA Plywood Diaphragm Guide was used to select plywood, and nailing requirements for the Table. Example: For a 1/2” … Webtural plywood sheathing, along with the floor or roof fram-ing that provides the required diaphragm capacity. Unblocked diaphragms do not have complete blocking along the panel edges that are perpendicular to the direction of the supporting framing span. Shear transfer along these edges is achieved by a combination of bearing

Use 18.5 mm Douglas fir plywood with 3” (3.66 mm diameter) nails spaced @ 64 mm o.c. at the blocked diaphragm boundaries and at continuous panel edges and 100 mm o.c. at other panel edges, 89 mm thick framing members minimum. Two lines of ... WebCalculating the nominal unit diaphragm shear capacity (plf) of such a connection is as follows: vn = 4.5 Z* (12 in/ft) / s The requirements and calculation method apply to the connections transferring diaphragm shear, including panel-to-panel, panel-to-chord, and panel-to-collector connections.
WebAllowable total load for floors is the least of load capacities for L/240, bending and shear. Allowable total load is therefore 173 psf. Live load is the lesser of the load for L/360, and total load, as determined above, minus dead load. WebFor example, if design shear for the construction requires a 15/32 inch minimum nominal panel thickness and the actual sheathing is 19/32 inch with all fasteners overdriven 1/8 inch, the net result is a 15/32 inch panel that meets the design shear requirements. 2.
