The shear and moment diagrams are shown in the figure. The displacements of the
diaphragm at grid line 3 are shown in Fig. 7.17, as previously discussed and shown in
Figs. 7.4 and 7.9. A complete example for the determination of the deflection produced
by shear wall rotation can be referenced in SEAOC's
Seismic Design Manual
, volume 2.

Figure 7.18 summarizes the method outlined in that manual for a single wall located at
the end of a supporting beam.
