Sentence 9.20.11.2.(2)

Intent 1:

To limit the probability of:

• inadequate interlocking of supporting walls with supported walls, and
• concentrations of stress at points of connection.

This is to limit the probability of failure of connections between intersecting walls under lateral loads, which could lead to an inability to transfer lateral loads from masonry walls to intersecting walls intended to provide lateral support, 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.

This is to limit the probability of:

• compromised structural integrity of masonry construction,
• where masonry construction is part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration, or
• an inability to resist expected loads, which could lead to excessive deflection or vibration of floors.

For floors and elements supporting floors, this is to limit the probability of persons losing their balance, tripping or falling, which could lead to harm to persons.
