1 Design information in this table is taken from ICC-ES ELC-3814 , dated April 2018 ,, table 23 and 24 , and converted for use with CSA A23.3 Annex D . 2 See figure 2 of section 3.2.4.3.1 . 3 Minimum edge distance may be reduced to 45mm provided rebar remains untorqued . See ESR-3814 section 4.1.9 . 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 Temperature range A : Max . short term temperature = 130 ° F ( 55 ° C ), max . long term temperature = 110 ° F ( 43 ° C ). Temperature range B : Max . short term temperature = 176 ° F ( 80 ° C ), max . long term temperature = 110 ° F ( 43 ° C ). Short term elevated concrete temperatures are those that occur over brief intervals , e . g ., as a result of diurnal cycling . Long term concrete temperatures are roughly constant over significant periods of time .

7 Bond stress values corresponding to concrete compressive stress ƒ ' _c = 2,500 psi ( 17.2 MPa ). For concrete compressive strength , ƒ ' _c

, between 2,500 psi

( 17.2 MPa ) and 8,000 psi ( 55.2 MPa ), the tabulated characteristic bond stress may be increased by a factor of ( ƒ ' _c / 2,500 ) ⁰ ^. ²⁵ [ for SI : ( ƒ ' _c

/ 17.2 ) ⁰ ^. ²⁵ ] for uncracked concrete and ( ƒ ' c

/ 2,500 ) ⁰ ^. ¹⁵ [ for SI : ( ƒ ' c / 17.2 ) ⁰ ^. ¹⁵ ] for cracked concrete . 8 For structures assigned to Seismic Design Categories C , D , E , or F , bond stress values must be multiplied by α _N _, _seis
