1 Design information in this table is taken from ICC-ES ESR-4386 , table 3 , and converted for use with CSA A23.3 Annex D . 2 See Figure 1 of this document . 3 The HSL4 is considered a ductile steel element as defined by CSA A23.3 Annex D section D . 2 . 4 For all design cases , ψ c , N = 1.0 . The appropriate coefficient for breakout resistance for cracked concrete ( k c , cr ) or uncracked concrete ( k c , uncr ) must be used . 5 For use with the load combinations of CSA A23.3 chapter 8 . Condition B applies where supplementary reinforcement in conformance with CSA A23.3 section D . 5.3 is not provided , or where pullout or pryout strength governs . For cases where the presence of supplementary reinforcement can be verified , the resistance modification factors associated with Condition A may be used . 6 For all design cases , ψ c , P = 1.0 . NA ( not applicable ) denotes that this value does not control for design . See section 4.1.4 of ESR-4386 for additional information . 7 HSL4-G M24 is not permitted for seismic applications .
