BRACED WALL LINE SPACING
|APPLICATION||CONDITION||BUILDING TYPE||BRACED WALL LINE SPACING CRITERIA|
|Maximum Spacing||Exception to Maximum Spacing|
|Wind bracing||Ultimate design wind speed 100 mph to < 140 mph||Detached, townhouse||60 feet||None|
|Seismic bracing||SDC A — C||Detached||Use wind bracing|
|SDC A — B||Townhouse||Use wind bracing|
|SDC C||Townhouse||35 feet||Up to 50 feet when length of required bracing per Table R602.10.3(3) is adjusted in accordance with Table R602.10.3(4).|
|SDC D0, D1, D2||Detached, townhouses, one- and two-story only||25 feet||Up to 35 feet to allow for a single room not to exceed 900 square feet. Spacing of all other braced wall lines shall not exceed 25 feet.|
|SDC D0, D1, D2||Detached, townhouse||25 feet||Up to 35 feet when length of required bracing per Table R602.10.3(3) is adjusted in accordance with Table R602.10.3(4).|
For SI: 1 foot = 304.8 mm, 1 square foot = 0.0929 m2, 1 mile per hour = 0.447 m/s.
Any portion of a wall along a braced wall line shall be permitted to angle out of plane for a maximum diagonal length of 8 feet (2438 mm). Where the angled wall occurs at a corner, the length of the braced wall line shall be measured from the projected corner as shown in Figure R602.10.1.4. Where the diagonal length is greater than 8 feet (2438 mm), it shall be considered a separate braced wall line and shall be braced in accordance with Section R602.10.1.
