GB = 1/2 minimum thickness gypsum board with 1 1/2 galvanized roofing nail or 1 1/4 screws, Type W or S for exterior sheathing, or 5d cooler nail, diame ter, 1 5/8 long, 15/64 head for interior sheathing. Maximum spacing of fasteners shall be at 7 on center, at panel edges including top and bottom plates. When Method GB panel s are applied to only one face of a braced wall panel, the minimum total length of braced wall panel in the Table shall be doubled. c. PCP = 7/8 minimum thickness portland cement plaster with 1 1/2 , 11 gage, 7/16 head nails at 6 spacing.

8 (For maximum 16 stud spacing only.) Gypsum wall board (1/2 minimum thickness) shall be installed on the side of the wall opposite the bracing material, except if the mi nimum total length of braced wall panel in the Table is multiplied by a factor of d. WSP = 15/32 minimum thickness wood structural panel with 8d common (2 1/2 x ) nails at 6 spacing (panel edge) at 12 spacing (intermediate supports), 3/8 edge distance to panel edge. Gypsum wall board (1/2 minimum thickness) shall be installed on the side of the wall opposite the bracing material, except if the minimum total length of braced wall panel in the Table is multiplied by a factor of e.

9 Method GB and PCP braced wall panel h/w ratio shall not exceed 1:1.
