Intent 1:

To limit the probability of inadequate end support, which could lead to inadequate stiffness or strength, which could lead to an inability to resist expected gravity loads, which could lead to:

• the excessive deflection of subfloors, or
• sagging or cracking of flexible or brittle finished floor between floor joists.

This is to limit the probability of an uneven walking surface, which could lead to persons tripping or falling, which could lead to harm to persons.
