To limit the probability of inadequate strength or corrosion resistance of anchors, which could lead to inadequate anchorage of floor or roof assemblies to masonry walls, which could lead to inadequate lateral stiffness, which could lead to an inability to resist lateral loads or inadequate distribution of gravity loads, which could lead to cracking or buckling.
Where masonry construction is required to provide fire resistance, this is to limit the probability of compromised fire resistance of the assembly, which could lead to harm to persons.
