steel anchors or toenailed. See Figure 11‑34. Some
joists need the support of a bearing wall or girder,

11.10 Ceiling Framing
A ceiling frame, as the name suggests, is the system of
support for all components of the ceiling. This frame
may be the underside of the floor joists for the next
story, the bottom chords of roof trusses, or ceiling
joists just below the roof. See Figure 11‑36. The basic
construction of an assembly just below the roof is simi-
lar to floor framing. The main difference is that lighter
joists are used and headers are not included around the
outside. When trusses are used to form the roof frame,
no additional ceiling frame is required.
