Concentrated Load on Wood Sheathing - plywood/osb
Concentrated Load on Wood Sheathing - plywood/osb
(OP)
I believe this has been asked before however there does not seem to be a definitive answer (or I didn't see it).
Does anyone have any examples/recomendations/referances for analysing a point load on plywood/osb floor.
I have found in the plywood specification that the punching shear may be the area of the point load x the perimeter. However how can bending and or deflection be addressed? Is there a reasonable tributary width to assume?
Thanks in advance.

APA's "Plywood Design Specification"
The last paragraph of Section 3.8.1 (Shear thru thickness) states:
"Shear-thru-the-thickness values as given in Table 3 shall also be used for 'punching shear' calculations. However, no increases in allowable stress shall be taken for face grain orientation, glued frame reinforcement, or restricted core gaps."
PS 1-83:
"Section 4.5.5 states that the general provisions of ASTM E661 are to be followed."
