Horizontal
members
Beams are horizontal load-bearing members supported at both ends. When
only one end is fixed, it is called a cantilever. Horizontal members that
support the weight of concrete or masonry walls above door and window
openings are called lintels. Sills, girts, or girders support the ends of floor
beams in wood-construction. Sills, sole plates, stud caps, rafter plates, and
top plates are horizontal members and were discussed in the previous
paragraph.
Figure 4-14 show examples of a cantilever and a lintel.
