allowable loads for APA rated plywood shear walls
allowable loads for APA rated plywood shear walls
(OP)
What are the allowable shear values for wind or seismic loading for wood structural panel shear walls?
The project is under the jurisdiction of the 2001 CBC. Should I be referencing NER-272 for the correct loads?
Thanks.

8d=0.131" dia.
10d=0.148" dia.
Thanks.

You will find design guides on shears wall, diaphragms etc....

You also need to be aware of the 3x stud and sill plate requirements in Footnote 3 for Zones 3 & 4.
Per your specific question, the loads in the table are for common nail sizes, which are as you list above. The reason for specifying the diameter is that gun nails come in a wide variety, but I've never been asked to specify the length of an 8d or 10d. Minimum penetration is not usually an issue nailing plywood.
These references are nice, but not a complete substitute for the code.

FYI
The next generation of California building codes is up in the air. The Building Standards Commission picked the NFPA5000 instead of the IBC, but there has been a large backlash. Its a mess.
California would be about the only jurisdiction in the country to choose the NFPA, with the exception of the city of Pasadena, TX. The plumbers and fire officials seem to like it, but engineers and architects are overwhelmingly against the NFPA and for the IBC.
