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

1 All values are for anchors installed in fully grouted concrete masonry with minimum masonry prism strength of 1,500 psi. Concrete masonry units shall be lightweight,
medium-weight or heavy-weight conforming to ASTM C90. Allowable loads are calculated using a safety factor of 5.
2 When using the basic load combinations in accordance with IBC Section 1605.3.1 or the alternative basic load combinations in IBC Section 1605.3.2. Tabulated
allowable loads must not be increased for seismic or wind loading.
3 One anchor shall be permitted to be installed in each concrete block.
4 Anchors are not permitted to be installed in a head joint, flange or web of the concrete masonry unit.
5 Allowable loads must be the lesser of the adjusted masonry or bond tabulated values and the steel values given in table 4.
6 Tabulated allowable loads shall be adjusted for increased base material temperatures in accordance with figure 12.
7 For combined loading: (T

) + (V

/ V

) ≤ 1
8 The tabulated edge distance is measured from the anchor centerline to the edge of the concrete block. See figure 2.
9 Linear interpolation of load values between the two tabulated edge distances is permitted.
