This is to limit the probability of compromised structural integrity, which could lead to:

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