<br /> 'For use with the load combinations of ACI 318 Section 9.2,Condition B applies where supplementary reinforcement In conformance.with ACI 318-11 D.4.3 is not
<br /> provided,or where pullout or pryout strength governs,For cases where the presence of supplementary reinforcement can be verified,the strength reduction factors
<br /> associated with Condition A may be used.
