Intent 1:

To limit the probability that the performance of steel, with respect to strength or stiffness, will fall significantly below expectations, which could lead to an inability to resist expected gravity loads, which could lead to excessive deflection.

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.
