1707.4.2 Interrupted Lateral Braces

2020 FBC - Existing Building, 7th edition > 17 Retrofitting > 1707 Lateral Braces > 1707.4 Alternative Installation > 1707.4.2 Interrupted Lateral Braces
JUMP TO FULL CODE CHAPTER

Where existing conditions prevent the installation of lateral braces of required length in accordance with Section 1707.1, a splice member shall be permitted to be installed to bridge interruptions. Splice members shall be at minimum the same size lumber as the lateral braces they bridge. Although Figure 1707.4.2 illustrates the general methods that can be used where attic-framing members are spaced 24-inches (610 mm) o.c., the methods apply to other on center spacings. Splice members may extend beyond those shown and are allowed to be fastened to the main lateral brace segments farther than shown. Splice members shall be fastened at each end using the number of fasteners equal to the total number that would be required to be placed in total in that part of lateral braces more distant from the gable end wall. For a lateral brace that requires three fasteners at each roof framing members and installation across three roof framing members, the number of fasteners in the splice need not be more than nine fasteners if the interruption is between the gable end wall and the first attic-framing member; six fasteners if between the first and second framing members, and three fasteners if between subsequent interruptions. Fasteners shall be spaced 1/2 inch (13 mm) from the edges of lateral braces, 1 inch from each other, 1/2 inch (13 mm) from the edge of attic members, and minimum 23/4 inches (25.4 mm) from the ends of lateral braces and from the ends of splice members.

For SI: 1 inch = 25.4 mm.
