Design information in this table is taken from ICC-ES ESR-2302 , dated December 1 , 2020 table 4 , and converted for use with CSA A23.3 Annex D .
2
See figure 1 of this section .
3
The stainless steel KWIK Bolt 3 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 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-2302 for additional information .
