9.23.11.3.(2)

Intent 1:

To limit the probability of inadequate capacity to transfer loads from supported floor and roof framing members in construction where a lintel will serve the function of a second top plate, which could lead to an inability to resist expected gravity and lateral loads, which could lead to:

• the inadequate distribution of vertical loads to and from studs, which could lead to the excessive deflection of wall plates, or
• inadequate diaphragm action of plates, which could lead to the excessive deflection of walls.

For floors and constructions supporting floors, this is to limit the probability of:

• compromised structural integrity, or
• for exterior floors or environmental separators supporting a floor, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of excessive movement, vibration or deflection of floors, which could lead to negative effects on the psychological well-being of persons.
