For SI: 1 inch = 25.4 mm, 1 psi = 0.006894 MPa. For pound-inch units: 1 mm = 0.03937 inch, 1 MPa = 145.0 psi.
1Bond strength values correspond to concrete compressive strength f'c = 2,500 psi. For concrete compressive strength, f'c between 2,500 psi and 8,000 psi, the
tabulated characteristic bond strength may be increased by a factor of (f'c / 2,500)0.12 [For SI: (f'c / 17.2)0.12]. See Section 4.1.4 of this report.
2Temperature Range A: Maximum long-term temperature = 110°F (43°C), maximum short-term temperature = 176°F (80°C). Temperature Range B: Maximum
long-term temperature = 110°F (43°C), maximum short-term temperature = 140°F (60°C). The maximum short-term temperature may be increased to 162°F
(72°C) for Temperature Range B provided characteristic bond strength are reduced by 10 percent.
3Short-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.
4Characteristic bond strengths are for sustained loads including dead and live loads. For load combinations consisting of short-term loads only such as wind or
seismic, bond strengths may be increased by 75 percent for Temperature Range A and Temperature Range B.
5Permissible installation conditions include dry concrete, water-saturated concrete and water-filled holes. Water-filled holes include applications in dry or water-
saturated concrete where the drilled holes contain standing water at the time of anchor installation. For installation instructions see Figure 2 of this report.
6For structures assigned to Seismic Design Categories C, D, E or F, bond strength values for cracked concrete do not require an additional reduction factor
applied (αN,seis = 1.0). See Section 4.1.11 of this report.
7Bond strength values for uncracked concrete are applicable for structures assigned to Seismic Design Categories A and B only.

For SI: 1 inch = 25.4 mm, 1 psi = 0.006894 MPa. For pound-inch units: 1 mm = 0.03937 inch, 1 MPa = 145.0 psi.
1Bond strength values correspond to concrete compressive strength f'c = 2,500 psi. For concrete compressive strength, f'c between 2,500 psi and 8,000 psi, the
tabulated characteristic bond strength may be increased by a factor of (f'c / 2,500)0.12 [For SI: (f'c / 17.2)0.12]. See Section 4.1.4 of this report.
2Temperature Range A: Maximum long-term temperature = 110°F (43°C), maximum short-term temperature = 176°F (80°C). Temperature Range B: Maximum
long-term temperature = 110°F (43°C), maximum short-term temperature = 140°F (60°C). The maximum short-term temperature may be increased to 162°F
(72°C) for Temperature Range B provided characteristic bond strength are reduced by 10 percent.
3Short-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.
4Characteristic bond strengths are for sustained loads including dead and live loads. For load combinations consisting of short-term loads only such as wind or
seismic, bond strengths may be increased by 67 percent for Temperature Range A and Temperature Range B.
5Permissible installation conditions include dry concrete, water-saturated concrete and water-filled holes. Water-filled holes include applications in dry or water-
saturated concrete where the drilled holes contain standing water at the time of anchor installation. For installation instructions see Figure 2 of this report.
6Bond strength values for uncracked concrete are applicable for structures assigned to Seismic Design Categories A and B only.
