Braced Wall Lines (BWL) and Braced Wall Panels (BWP)
Bracing is required in accordance with R602.10. All exterior and interior
walls parallel to a Braced Wall Line shall be offset not more than 4 feet and
Braced Wall Panels shall be full-height sections with no vertical or
horizontal offsets (R602.10.2).
BWP shall begin within 10 feet from each end of a braced wall line.
Distance between Braced Wall Panels in a Braced Wall Line shall be no
greater than 20 feet. (R602.10.2.2).
Per R602.10.2.3 a BWL with a length of 16' or less shall have a minimum
of two braced wall panels of any length or one BWP equal to or greater
than 48”. BWL greater than 16' shall have a minimum of two BWP.
The end of a BWL shall be the intersection with a perpendicular BWL
(R602.10.1.1). For additional spacing information see Tables R602.10.3
CONTINUOUS SHEATHING METHOD (R602.10.4.2) require structural panel
sheathing to be used on ALL sheathable surfaces ON ONE SIDE of a Braced
Wall Line, including ares above and below openings and gable end walls
(R602.10.7). See Figure R602.10.7 for the five acceptable End Conditions.
There are 16 Bracing Methods in addition to Continuous Sheathing allowed
(R602.10.4); the most common ones are listed below.

*Note: When exterior wall shear wall lines or Braced Wall Panels are
not in one plane vertically from the foundation to uppermost story,
the following conditions must be met:
1.Floor joists must be 16" o.c. or closer
2.Ratio of back span of a cantilever is no greater than 2:1
3.Floor joists at the ends of the Braced Wall Panels are doubled
4.A continuous rim joist is used
5.Gravity loads are uniform.
