1. The information presented in this table is to be used in conjunction with the design criteria of ACI 318-11. 2. Temperature Range: Maximum short-term temperature of 150°F (66ºC). Maximum long-term temperature of 110°F (43°C). 3. Short-term concrete temperatures are those that occur over short intervals (diurnal cycling). 4. Long-term concrete temperatures are constant temperatures over a significant time period. 5. For anchors that only resist wind or seismic loads, bond strengths may be multiplied by 2.70. 6. The value of φ 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 to Section D.4.5 to determine the appropriate value of φ. 7. The value of φ applies when both the load combinations of ACI 318 Section 9.2 are used and the requirements of Section D.4.4 (c) for Condition B are met. If the load combinations of ACI 318 Appendix C are used, refer to Section D.4.5 to determine the appropriate value of φ. 8. The value of φ applies when both the load combinations of ACI 318 Section 9.2 are used and the requirements of Section D.4.4 (c) for Condition B are met. If the load combinations of ACI 318 Section 9.2 are used and the requirements of Section D.4.4 (c) for Condition A are met, refer to Section D.4.4 to determine the appropriate value of φ. If the load combinations of ACI 318 Appendix C are used, refer to Section D.4.5 to determine the appropriate value of φ.

9. For anchors installed in regions assigned to Seismic Design Category C, D, E or F, the bond strength values for 3/8" and 1 1/4" anchors must be multiplied by αN,seis = 0.78. 10. For anchors installed in regions assigned to Seismic Design Category C, D, E or F, the bond strength values for 1/2", 5/8" and 3/4" anchors must be multiplied by αN,seis = 0.85. 11. For anchors installed in regions assigned to Seismic Design Category C, D, E or F, the bond strength values for 7/8" anchors must be multiplied by αN,seis = 0.82. 12. For anchors installed in regions assigned to Seismic Design Category C, D, E or F, the bond strength values for 1" anchors must be multiplied by αN,seis = 0.70. 13. For applications where maximum short-term temperature is 110ºF (43ºC) and the maximum long-term temperature is 75°F (24°C), bond strengths may be multiplied by 3.50. No additional increase is permitted for anchors that only resist wind or seismic loads.

1. Tension design strength must be the lesser of the concrete, bond or threaded rod steel design strength. 2. Tension design strengths are based on the strength design provisions of ACI 318-11 Appendix D assuming dry concrete, periodic inspection, short-term temperature of 150°F and long-term temperature of 110°F. 3. Tabulated values are for a single anchor with no influence of another anchor. 4. Interpolation between embedment depths is not permitted. 5. Strength reduction factor, f, is based on using a load combination from ACI 318-11 Section 9.2. 6. The tension design strength listed for SDC (Seismic Design Category) A-B may also be used in SDC C-F when the tension component of the strength-level seismic design load on the anchor does not exceed 20% of the total factored tension load on the anchor associated with the same load combination. 7. When designing anchorages in SDC C-F, the Designer shall consider the ductility requirements of ACI 318-11 Section D.3.3. Design strengths in Bold indicate that the anchor ductility requirements of D.3.3.4.3 (a)1 to 3 are satisfied when using ASTM F1554 Grade 36 threaded rod. Any other ductility requirements must be satisfied. 8. Tension design strengths in SDC C-F have been adjusted by 0.75 factor in accordance with ACI 318-11 Section D.3.3.4.4.

1. Allowable tension load must be the lesser of the concrete, bond or threaded rod steel load. 2. Allowable tension loads are calculated based on the strength design provisions of ACI 318-11 Appendix D assuming dry concrete, periodic inspection, short-term temperature of 150°F and long-term temperature of 110°F. Tension design strengths are converted to allowable tension loads using a conversion factor of a = 1.4. The conversion factor a is based on the load combination 1.2D + 1.6L assuming 50% dead load and 50% live load: 1.2(0.5) + 1.6(0.5) = 1.4. 3. Tabulated values are for a single anchor with no influence of another anchor. 4. Interpolation between embedment depths is not permitted.

ET-HP® Tension Design Strengths for Rebar in Normal-Weight Concrete (f'c = 2,500 psi)

1. Tension design strength must be the lesser of the concrete, bond or rebar steel design strength. 2. Tension design strengths are based on the strength design provisions of ACI 318-11 Appendix D assuming dry concrete, periodic inspection, short-term temperature of 150°F and long-term temperature of 110°F. 3. Tabulated values are for a single anchor with no influence of another anchor. 4. Interpolation between embedment depths is not permitted. 5. Strength reduction factor, f, is based on using a load combination from ACI 318-11 Section 9.2. 6. The tension design strength listed for SDC (Seismic Design Category) A-B may also be used in SDC C-F when the tension component of the strength-level seismic design load on the anchor does not exceed 20% of the total factored tension load on the anchor associated with the same load combination. 7. When designing anchorages in SDC C-F, the Designer shall consider the ductility requirements of ACI 318-11 Section D.3.3. 8. Tension design strengths in SDC C-F have been adjusted by 0.75 factor in accordance with ACI 318-11 Section D.3.3.4.4.

Minimum Dimensions for Cracked (in.)

1. Allowable tension load must be the lesser of the concrete, bond or rebar steel load. 2. Allowable tension loads are calculated based on the strength design provisions of ACI 318-11 Appendix D assuming dry concrete, periodic inspection, short-term temperature of 150°F and long-term temperature of 110°F. Tension design strengths are converted to allowable tension loads using a conversion factor of a = 1/0.7 = 1.43. The conversion factor a is based on the load combination assuming 100% seismic load. 3. Tabulated values are for a single anchor with no influence of another anchor. 4. Interpolation between embedment depths is not permitted. 5. The allowable tension load listed for SDC (Seismic Design Category) A-B may also be used in SDC C-F when the tension component of the strength-level seismic design load on the anchor does not exceed 20% of the total factored tension load on the anchor associated with the same load combination. 6. When designing anchorages in SDC C-F, the Designer shall consider the ductility requirements of ACI 318-11 Section D.3.3. 7. Allowable tension loads in SDC C-F have been adjusted by 0.75 factor in accordance with ACI 318-11 Section D.3.3.4.4.

1. Edge distance (Ccr or Cmin) is the distance measured from anchor centerline to edge or end of CMU masonry wall. Refer to Figure 2 below for an illustration showing critical and minimum edge and end distances. 2. Anchor spacing (Scr or Smin) is the distance measured from centerline to centerline of two anchors. 3. Critical edge distance, Ccr, is the least edge distance at which tabulated allowable load of an anchor is achieved where a load reduction factor equals 1.0 (no load reduction). 4. Minimum edge distance, Cmin, is the least edge distance where an anchor has an allowable load capacity which shall be determined by multiplying the allowable loads assigned to anchors installed at critical edge distance, Ccr, by the load reduction factors shown above. 5. Critical spacing, Scr, is the least anchor spacing at which tabulated allowable load of an anchor is achieved such that anchor performance is not influenced by adjacent anchors. 6. Minimum spacing, Smin, is the least spacing where an anchors has an allowable load capacity, which shall be determined by multiplying the allowable loads assigned to anchors installed at critical spacing distance, Scr, by the load reduction factors shown above. 7. Reduction factors are cumulative. Multiple reduction factors for more than one spacing or edge or end distance shall be calculated separately and multiplied. 8. Load reduction factor for anchors loaded in tension or shear with edge distances between critical and minimum shall be obtained by linear interpolation. 9. Load reduction factor for anchors loaded in tension with spacing between critical and minimum shall be obtained by linear interpolation. 10. Perpendicular shear loads act towards the edge or end. Parallel shear loads act parallel to the edge or end (see Figure 3 below). Perpendicular and parallel shear load reduction factors are cumulative when the anchor is located between the critical minimum edge and end distance.

1. E = Embedment depth (inches). 2. Sact = actual spacing distance at which anchors are installed (inches). 3. Scr = critical spacing distance for 100% load (inches). 4. Smin = minimum spacing distance for reduced load (inches). 5. fs = adjustment factor for allowable load at actual spacing distance. 6. fscr = adjustment factor for allowable load at critical spacing distance. fscr is always = 1.00. 7. fsmin = adjustment factor for allowable load at minimum spacing distance. 8. fs = fsmin + [(1 – fsmin) (sact – smin) / (scr – smin)].
