An approved plan defines a single braced wall line using two parallel wall runs of 24 feet and 14 feet, connected by a 3-foot perpendicular jog. For this exercise the plan specifies the projected line length as 24 + 14 feet, excludes the jog from that length, and requires bracing equal to 25 percent of the line length. How much bracing is required?
- 9 feet 6 inches
- B10 feet 3 inches
- C6 feet 0 inches
- D7 feet 7 inches
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why A is correct
The supplied plan defines a 38-foot line. Required bracing is 38 × 0.25 = 9.5 feet, or 9 feet 6 inches. Adding the perpendicular jog would produce 41 feet and 10 feet 3 inches, contrary to the stated plan definition. This calculation does not independently approve the offset, bracing method or panel placement.
