Cal. Civ. Code § 110-11-1-.06

The following amendments to codes are hereby adopted by the
Board of Community Affairs as amendments to the Georgia State Minimum Standard
Codes for Construction:

GEORGIA AMENDMENTS TO THE

1994 STANDARD BUILDING CODE

Add to Section 202, Definitions, a definition for "Shearwall
Segment" as follows:

SHEARWALL SEGMENT - a wall or portion thereof which transfers
in plane lateral shear loads to a wall or foundation below and resists
overturning.

* Said building code is further amended by adding an
"Exception 5" to Section 1606.1.1 Determination of Wind Forces, as
follows:

Exceptions:

5. Provisions of AF&PA "Wood Frame Construction Manual
for One-and-Two Family dwellings - 1995 SBC High Wind Edition" shall be
permitted for applicable wood frame buildings of Group R3 occupancy

* Said building code is further amended by adding a Section
2313 entitled "Perforated Shearwalls" as follows:

2313 Wind Provisions

2313.1 General

All buildings for which a wind analysis is required,
according to 1606.1 and which are constructed partially or wholly of wood or
wood based materials shall be designed in accordance with the provisions of
2313 and Chapter 23.

2313.2.1 Shearwall Segments

The total allowable shearwall capacity (lbs.) of each
full-height shearwall segment without openings shall be equal to the allowable
shear capacity (plf) times the length of the wall segment. Where the dead load
stabilizing moment per 1606.4 is not sufficient to prevent overturning due to
moment loads on the wall, an anchoring device with a capacity equal to the
allowable shear capacity (p11) times the wall height shall be provided at each
end of the shearwall segment. All anchoring devices shall maintain a continuous
load path to the foundation. The capacity of shearwalls with openings shall be
adjusted in accordance with 2313.2.2

2313.2.2 Openings in Shearwalls

Where openings are located within the shearwall segment, the
wall shall be entirely sheathed with structural sheathing, including areas
above and below openings. If areas above and below remain unsheathed, the
height of the unrestrained openings shall be the height of the wall. The
allowable shear capacity (p11) determined in 2313.2.1 shall be adjusted in
accordance with Table 2313.2.2 based upon the maximum opening height and the
percentage of shearwall segments containing full-height sheathing. The total
allowable shear capacity (lbs.) shall be equal to the adjusted allowable shear
capacity (plf) times the length of full-height sheathing.

1. H - the height of the tallest opening in the
shearwall.

2. The sum of the length of a shearwall that is sheathed its
full height divided by the length of the shearwall segment.

2313.2.3 Shear Capacities of Dissimilar Materials.

The allowable shear capacity of shearwall segments sheathed
on both sides, with similar or dissimilar materials, shall equal the sum of the
shear capacity of each separate side.

2313.2.4 Wood Structural Panel Diaphragm Shear
Capacities.

The allowable shear capacities in Table 23 l0.2A for
horizontal wood structural panel diaphragms shall be increased 40 percent for
wind design.

2313.2.5 Wood Structural Panel Shear Wall Capacities.

The allowable shear capacities in Table 23 l0.2B for wood
structural panel shear walls shall be increased 40 percent for wind
design.

2313.3 Wall Stud Bending Stress Increases

The fiber stress bending (Fb) design values for wood studs,
in the NDS supplement shall be increased by the factors in Table 2313.3, in
lieu of the 1.15 repetitive member factor to take into consideration the load
sharing and composite actions provided by the structural sheathing. Where the
studs are designed for bending in accordance with 1606.2.5, spaced no more than
16 inches on center, covered on the inside with a minimum of 1/2 inch gypsum
board fastened in accordance with Table 2306.1, or its equivalent, and sheathed
with a minimum of 3/8 inch structural sheathing that is attached to the studs
using a minimum of 8d common nails spaced a maximum of 6" o.c. at panel edges
and 12" o.c. in the field of the panels.
