9.15.4.10. Interior Masonry Walls
This Article points to the requirements in NBC Section 9.20. for interior masonry walls acting as foundation# walls so that they are constructed to have adequate strength to support anticipated loads.
The minimum #width for an interior loadbearing masonry# wall depends on the spacing of its lateral support. Such walls must be laterally supported by floor or roof construction, or by intersecting masonry walls or #buttresses. The maximum spacing of such supports can be no greater than 20 times the wall thickness, as illustrated in Figure 9.15.-18 (NBC Article 9.20.10.1.).
