1 Design information in this table is taken from ELC-4868 , tables 8 and 10 for use with CSA A23.3 Annex D . 2 See figure 10 of this section . 3 Minimum edge distance may be reduced to 45mm ≤ c ai
< 5d provided T inst is reduced . See ELC-4868 Installation Torque Subject to Edge Distance section .
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 ). 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 .
7 Bond strength values corresponding to concrete compressive strength 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 strength may be increased by a factor of ( ƒ ' c / 2,500 ) 0 . 1 [ for SI : ( ƒ ' c
/ 17.2 ) 0 . 1 ].
8 For water-filled holes , multiply characteristic bond stress by 0.61 .
