1 Design information in this table is based on testing in accordance with ACI 355.4 . 2 See Figure 4 . 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 Values provided for post-installed anchors under Condition B without supplementary reinforcement as defined in CSA A23.3 Section D . 5.3 .
For cases where the presence of supplementary reinforcement can be verified , the reduction 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 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 ., 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 7 Characteristic bond strengths are for horizontal and vertical downward direction only . For overhead ( vertical up ) installation , bond strengths must be multiplied by 0.70 .
