[F22-OS3.7] Applies to walls, and elements that support walls, that contain doors or windows required for emergency egress.
Application
Application 1: 
Minimum dimensions, material, and fastening of ties for top wall plates that are not lapped at corners and intersections and of ties for joints in single plates, in loadbearing wood-frame walls to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].

Intent
Intent 1: 
To limit the probability of inadequate continuity of joints in single top plates, which could lead to an inability to resist expected lateral loads, which could lead to the excessive deflection or failure of wall plates.
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.
