JUMP TO FULL CODE CHAPTER

Truss gable end walls shall be attached to the wall below using gusset angle brackets fastened to the bottom chord of roof trusses and to the wall below and spaced in accordance with Table 1704.1. Fasteners shall be placed a minimum of 5/8 inch (15.875 mm) from edges of lumber. Fasteners shall be permitted to penetrate truss plates. Four fasteners shall be effectively installed through each leg of gusset angles.

Exception: Where existing conditions prevent effective installation of all four fasteners into each leg of a gusset angle bracket, a supplementary gusset angle bracket shall be installed a minimum of 23/4 inches (70 mm) from and a maximum of 8 inches (203 mm) from the one without the four fasteners in each leg. The number of effectively installed fasteners securing the corresponding leg of the supplementary gusset angle bracket shall at least equal the number not effectively installed on the first gusset angle bracket.

1709.1.1.1 Wood Frame Wall Below

Where the wall below a gable end is a wood frame wall, a gusset angle bracket specified by the manufacturer for lumber-tolumber applications shall be installed using fasteners of the same type supplied/specified by the manufacturer. Fasteners installed in top plates shall extend through the full depth of the lowest top plate.

1709.1.1.2 Concrete or Masonry Wall Below

Where the wall below a gable end wall is a concrete or masonry wall, connections shall be by one of the following methods.

1709.1.1.2.1

Where the wall below does not have a sill plate on top of the bond beam, a gusset angle bracket specified by the manufacturer for lumber-toconcrete or lumber-to-masonry applications shall be installed directly to the concrete or masonry of the wall below and to the bottom chord of the truss.

1709.1.1.2.2

Where there is a sill plate of any thickness on top of the bond beam a gusset angle bracket specified by the manufacturer for lumber-to-concrete or lumber-to-masonry applications shall be installed on the sill plate with fasteners passing vertically through the gusset angle bracket and sill plate and connecting directly into the concrete or masonry wall below. Fasteners of the same diameter and style supplied/specified by the gusset manufacturer shall be installed that have sufficient length to penetrate the sill plate and embed into the concrete or masonry to the same depth provided by the fasteners supplied/specified by the gusset angle bracket manufacturer for installation directly into concrete.

1709.1.1.2.3

Where there is a sill plate on top of the bond beam that is a minimum 11/2 inches (38 mm) thick, a gusset angle bracket specified by the manufacturer for lumber-to-lumber applications shall be fastened to the sill plate. Gusset angle brackets shall be fastened to the sill plate using four each 11/2-inch (38 mm) long fasteners of the same type supplied/ specified by the gusset angle manufacturer for wood connections. Regardless of how well the sill plate may be attached to the wall, it shall be anchored to the wall below on each side of the gusset angle bracket using concrete screws of the same type and size and number as those supplied/specified by the gusset manufacturer for concrete or masonry connections. They shall be embedded into the concrete or masonry to the same depth intended for the fasteners supplied/specified by the manufacturer of gusset angles installed in concrete. Washers of minimum 3/8-inch (9.5 mm) diameter shall be placed under heads of those fasteners. Fasteners shall be placed a minimum of 23/4 inches (70 mm) and a maximum of 8 inches (203 mm) from the required gusset angle bracket.
