- The information presented in this table is to be used in conjunction with the design criteria of ICC-ES AC308, except as modified below.
- Temperature Range 1: Maximum short-term temperature of 110°F (43°C). Maximum long-term temperature of 75°F (24°C).
- Temperature Range 2: Maximum short-term temperature of 150°F (66°C). Maximum long-term temperature of 110°F (43°C).
- Short-term concrete temperatures are those that occur over short intervals (diurnal cycling).
- Long-term concrete temperature are constant temperatures over a significant time period.
- For anchors that only resist wind or seismic loads, bond strengths may be increased by 72%.
- In water-saturated concrete, multiply τk,uncr and τk,cr by Ksat.
- For anchors installed in overhead and subjected to tension resulting from sustained loading, multiply the value calculated for Na according to ICC-ES AC308 by 0.75. .
- The value of
applies when the load combinations of ACI 318 Section 9.2 are used. If the load combinations of ACI 318 Appendix C are used, refer toSection D.4.5 to determine the appropriate value of . - The value of applies when both the load combinations of ACI 318 Section 9.2 are used and the requirements ofSection D.4.4(c) for Condition B are met. If the load combinations of ACI 318 Appendix C are used, refer toSection D.4.5 to determine the appropriate value of .

- Sand-lightweight and all-lightweight concrete are beyond the scope of this table.
- For anchors installed in regions assigned to Seismic Design Category C, D, E or F, the bond strength values for 7/8" anchors or #7 rebar anchors must be multiplied by αN,seis = 0.80.
- For anchors installed in regions assigned to Seismic Design Category C, D, E or F, the bond strength values for 1" anchors or #8 rebar anchors must be multiplied by αN,seis = 0.92
- The values of f'c used for calculation purposes must not exceed 8,000 psi (55.1 MPa) for uncracked concrete. The value of f'c used for calculation purposes must not exceed 2500 psi (17.2 MPa) for cracked concrete.
