For use with the load combinations of ACI 318-14 Section 5.3, ACI 318-11 Section 9.2 or IBC Section 1605.2. Condition B applies where
supplementary reinforcement in conformance with ACI 318-14 17.3.3(c) or ACI 318-11 Section D.4.3(c) is not provided, as applicable, or where pull-out
or pry out strength governs. For cases where the presence of supplementary reinforcement can be verified, the strength reduction factors associated
with Condition A may be used.
