Application | Application 1: Anchor bolts for securing ledger boards to flat insulating
concrete form walls to support floor joists, where walls are not in contact
with the ground, in buildings to which Part 9 applies
[see Sentence 1.3.3.3.(1) of Division A for application of Part 9], and

Intent | Intent 1: To limit the probability that ledger boards will not be
adequately attached, which could lead to inadequate end support of floor joists,
which could lead to an inability to resist expected gravity loads, which could
lead to the excessive movement, deformation or failure of floor assemblies.
This is to limit the probability of compromised structural integrity,
which could lead to:
This is to limit the probability of harm to persons.
