FBC 2014 CH 23 change
(OP)
Good afternoon all,
In the latest version of the FBC, Table 2306.2 (1) only includes allowable shear values for 1-1/2” 16 gage staples. However, in previous versions of the FBC, nails (whether 8d or 10d) and staples were included for allowable shear design values for structural diaphragms. My question is: Why? Why did nails get removed from the table? Is there any documentation I can follow that would provide me with nailing capacities? I cannot find anything within the code itself, or any other documentation online to explain the change.
Does anyone have any idea the code officials would do this? I have emailed someone at DBPR but haven't received a response yet.
Below are the two tables

It is also probably good to note, the same tables and values are in the 2009 and 2012 IBC, as I believe the Florida Building Code is based off IBC.
It just doesn't make sense that code officials would only specify staples instead of nails, considering that Miami-Dade County has outlawed staples since Hurricane Andrew.

"Jenna, the said change was made at the national level through the International Code Change process for the 2009 IBC. The reason for the change is that nails values are available from ANSI/AF&PA NDS Supplement for Special Design Provisions for Wind and Seismic (SDPWS) which is currently adopted by reference in the code."
I guess I didn't see it explicitly in the code, so I didn't realize it was linked to SDPWS.
Thanks again all!
