1707.6 Installation at Truss Ridges
JUMP TO FULL CODE CHAPTER
Where existing conditions prevent installation of lateral braces near the peak of roofs, ridge ties made of minimum 2 × 4 members shall be installed horizontally on faces of trusses to provide anchorage for a required lateral brace. The bottom surfaces of added ridge tie members shall be aligned so that they will support a continuous lateral brace and be installed a maximum of 4 inches (102 mm) below limiting existing conditions for any of the trusses used to support the lateral brace. Ridge ties shall be installed on a minimum of three trusses and on every truss member over which lateral braces pass and be attached to an attic-framing member at least 6 feet (1829 mm) from the exterior sheathing or siding on the gable end wall. Ridge ties shall be placed on alternate sides of trusses. Ridge ties used to support lateral braces shall be fastened to each top chord member of each truss using two (2) 3-inch long fasteners and to any other truss members they cross using three (3) 3-inch long fasteners. Fasteners shall be spaced a minimum 1/2 inch (13 mm) from edges of all members and minimum of 1-inch (25.4 mm) from each other. Lateral braces shall be attached to ridge ties as required by Section 1707.3.1.
