1 Design information in this table is taken from ICC-ES ESR-4372 , dated May , 2019 ,
Tables 4 and 5 , and converted for use with CSA A23.3 Annex D . 2 See Figure 2 . 3 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 . 4 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 .
5 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 ). Temperature range C : Max . short term temperature = 248 ° F ( 120 ° C ), max . long term temperature = 162 ° F ( 72 ° 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 .

6 Bond strength values corresponding to concrete compressive strength f ́c = 2,500 psi ( 17.2 MPa ). For concrete compressive strength , f ́c , between 2,500 psi ( 17.2 MPa ) and 8,000 psi ( 55.2 MPa ), the tabulated characteristic bond strength may be increased by a factor of ( f ́c / 2,500 ) n [ for SI : ( f ́c / 17.2 ) n ]. where n is as follows : n = 0.26 for uncracked concrete n = 0.14 for cracked concrete
7 For 3 / 8-in . to 1-in . rods , characteristic bond strengths are for horizontal and vertical downward direction only . For overhead ( vertical up ) installation , bond strengths must be multiplied by 0.70 .
8 1-1 / 4-in . diameter rods to be installed in generally vertically downward direction only .
