(b) All panel edges backed with 2-in.nominal or wider framing.Install panels either horizontally or vertically.Space nails maximum 6 in.o.c.along intermediate framing members for 3/8 Category and 7/16 Category panels installed on studs spaced 24 in.o.c.For other conditions and panel thicknesses,space nails maxi- mum 12 in.o.c.on intermediate supports. Fasteners shall be located 3/8 in.from panel edges. (c) Allowable shear values are permitted to be increased to values shown for 15/32 category sheathing with same nailing provided(1)studs are spaced a maximum of 16 in.o.c.,or(2)panels are applied with long dimension across studs. (d) Framing at adjoining panel edges shall be 3-in.nominal or wider,and nails shall be staggered where nails are spaced 2 in.o.c.Check local code for variations of these requirements, (e) Framing at adjoining panel edges shall be 3-in.nominal or wider,and nails shall be staggered where 10d nails(3 in.x 0.148 in.)having penetration into framing of more than 1-1/2 in.are spaced 3 inches o.c.Check local code for variations of these requirements. (f) Where panels are applied on both faces of a wall and nail spacing is less than 6 in.o.c.on either side,panel joints should be offset to fall on different framing members. Or framing shall be 3 in.nominal or thicker and nails on each side should be staggered. (g) In Seismic Design Category D,E,or F,where shear design values exceed 350 pounds per lineal foot,all framing members receiving edge nailing from abutting panel edges shall not be less than a single 3-in.nominal member,or two 2-in.nominal members fastened together in accordance with 2006 IBC Section 2306.1 to transfer the design shear value between framing members.Wood structural panel joint and sill plate nailing shall be staggered in all cases.See 2006 IBC Section 2305.311 for sill plate size and anchorage requirements. (h) Galvanized nails should be hot dipped or tumbled. (i) For shear loads of normal or permanent load duration as defined by the AF&PA NOS,the values in the table above should be multiplied by 0.63 or 0.56 respectively. **Performance Category replaces the fractional nominal thickness used in P52.
