Intent
Intent 1: 
To limit the probability of an inadequate connection between wall assemblies that provide transverse support, which could lead to an inability to resist expected lateral loads, which could lead to the excessive deflection or failure of walls.
Where walls support floors, this is to limit the probability of:
  • the excessive deformation of floors, which could lead to compromised operation of doors required for egress in an emergency, or
  • the excessive deflection or vibration of floors, which could lead to persons losing their balance, tripping or falling.
This is to limit the probability of harm to persons.
Intent 2: 
To provide a cross-reference to Sentence 9.23.11.4.(4) and thereby further define its application.
