Codes & Standards Discussion Forum 

Welcome to the ICC Codes & Standards Discussion Forum

The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.

Bill,
As you know, you are in a seismic zone.
This should be engineered as the floor will probably act as a diaphragm (transmits lateral forces to the walls and/or foundations).
I assume this is for a house?
I''d suggest that you glue and screw the subfloor to the floor joists as this will reduce squeaky floors.
Hope this helps

Section 2320.9.1 California building code
Sheathing used as a structural subfloor shall conform to the limitations set forth in tables 23-II-D-1 and 23-II-D-2?? Subflooring maybe omitted when the joists spacing does not exceed 16" and 1" nominal T&G wood strip flooring is applied perpendicular to the joists.

The size of required nails are based on the thickness of the Subfloor. refer to Table 23-II-B-1.
It is not required though recommended to apply construction adhesive to the joists.

FYI
Typ. 3/4" T&G rated sheathing ( ply / osb ).
Divide 32 by the sq. footage of your floor. Add about 10% ( 15 - 20% if the floor is complex or cut up).
PL400 construction adhesive. About 2 tubes per every 3 sheets.
1 to 2 50lbs. boxes 10D ring gun nails.
This is basic, don''t know your situation.
Hope that helps.

Thats Great But:
1. It''s not the code info he was looking for.
2. In production housing they don''t always use 3/4" T&G< maytimes it''s 5/8".

Your right. Here in Calif. I mostly see 95% 3/4" and 5% 1 1/8". After all that 3/4", the 5/8" fells a little spongy.
Just wanted to pass on some info of what I would typ. see.
I forgot, the nails are 6" at edges and 12" in the field. Go 5 and 10, and shot it down as soon as you can after gluing.

The original posting was asking for code not for feelings.
