from hollow masonry units, the units are positioned so that their cores align verti-
cally to permit placement of reinforcing bars in the cells and flow of grout (Fig. 6.6c).
Structural considerations may necessitate grouting of only those cells that contain rein-
forcement, forming what is called a partially grouted wall. Figure 6.7 shows ways of
providing vertical and horizontal reinforcement in masonry walls. Partial grouting is
advantageous in that it affords saving of grout and, consequently, a lighter structure.
A lighter structure offers the advantage of causing smaller inertia (or lateral seismic)
forces, resulting in an economical design.
