Wood Floor Joists
Wood floor joists normally have a 3-in. fire cut end and bear only on the interior wythe of a cavity wall. If the ends project into the cavity, they can form a ledge which may create a moisture bridge across the cavity.
All building codes require joists to be anchored to masonry walls at specified intervals in a prescribed manner. Codes generally require an anchor at the end of every fourth joist. Where the joists are parallel to a wall, anchors engage 3 joists at intervals not exceeding 8 ft (2.438 m). Cavity wall ties are usually required within 8 in. (203 mm) of joist bearing level. With such construction, the floor is considered to provide lateral support for the walls, see Fig. 4.
Wood Rafter Plates
Wood roofs can be anchored to cavity walls by many methods, two of which are shown in Fig. 5. The detail
