11.4.1 Built in (Encastre)

Runways may be built directly into suitable walls. Figure 11.4.1-1  a shows a cantilever runway built directly into a concrete structure. A runway, built into a brick structure, is shown in Figure 11.4.1-1  b, and is considered to be a simply supported beam. In this case, note the padstones distributing the resulting crushing loads imposed on the bricks at the bearing points.
