Figure 1-16. Reinforced joists
b. Joists and Sills. When joining joists to sills, be sure that the connection can hold the load
that the jolt will carry. A joist resting on the sill and girder is shown in Figure 1-17. This connection
method is most commonly used because it provides the strongest possible joint. The method shown in
Figure 1-18, page 1-14, a joist with ledger plates is used when it is not desirable to use joists on top of
the sill. The ledger plate should be securely nailed to the sill and girder. If the joist must be notched, it
should be securely nailed to the sill and girder. If the joist must be notched, it should not be notched
over one third of its depth (to prevent splitting). Joists must be level when framed to girders. If the
joist is not the same height as the girder, the joist must be notched (see Figure 1-19, page 1-14).
