Objective | OS2 Structural Safety |
Attribution | |
Application | Application 1: Minimum compressive strength of cast-in-place concrete
that is not required to be reinforced that is used in garage and carport floors
and exterior steps, including steps providing structural support (to guards or handrails, for example), where exposure to
de-icing salts, water from rain or melting snow, freezing and thawing stresses,
traffic, abrasion or other severe exposure conditions is likely.
This applies to buildings to which Part
9 applies [see Sentence 1.3.3.3.(1) of Division A for application of
Part 9].

Intent | Intent 1: To limit the probability of an inadequate resistance to
freeze-thaw stresses, de-icing salts, abrasion or traffic, which could lead
to the excessive shrinkage, cracking and premature failure of concrete.
This is to limit the probability of compromised structural integrity,
which could lead to structural failure, which could lead to harm to persons.
