For SI: 1 inch = 25.4 mm, 1 lbf = 4.45 N, 1 psi = 6.89 kPa.
1
All values are for anchors installed in fully grouted concrete masonry with minimum masonry strength of 1500 psi. Concrete masonry units must be light-,
medium-, or normal-weight conforming to ASTM C90. Allowable loads have been calculated using a safety factor of 5.
2
When using the basic load combinations in accordance with IBC Section 1605.3.1, tabulated allowable loads must not be increased for seismic or wind
loading. For the 2021, 2018, 2015 and 2012 IBC, the allowable loads or load combinations must not be adjusted.
3
One anchor must be permitted to be installed in each CMU block. Refer to Figure 3 for an illustration of the anchor location for which the tabulated values are
applicable.
4
The tabulated edge distance is measured from the anchor centerline to the edge of the CMU block as depicted in Figure 3.
5
Anchors must be installed into the grouted cell. Anchors are not permitted to be installed in a head joint, flange or web of the concrete masonry unit.
6
Linear interpolation of load values between the two tabulated edge distances is permitted, as applicable
7
Allowable loads must be the lesser of the adjusted masonry or bond values tabulated above and the steel values given in Tables 4 and 5.
8
Tabulated allowable bond loads must be adjusted for increased base material temperatures in accordance with Figure 1, as applicable.

1
Allowable load used in the design must be the lesser of bond values and tabulated steel values.
2
Allowable tension and shear loads for threaded rods to resist short term loads, such as wind or seismic, must be calculated in accordance with Section 4.1 as
applicable.
3
Allowable steel loads are based on allowable tension and shear stresses equal to 0.33 x F
u
and 0.17 x F
u
, respectively.
