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 mortar joint of the concrete masonry unit . 5 Allowable loads must be the lesser of bond tabulated values and the steel values given in tables 3 and 4 . 6 Tabulated allowable loads shall be adjusted for increased base material temperatures in accordance with figure 13 . 7 Anchors installed on the side of the wall , shall have minimum of 16 " vertical spacing . 8 For combined loading : ( T applied
/ T allowable ) + ( V applied
/ V allowable ) ≤ 1 , where n = 5 / 3 for 1 / 2-inch diameters (# 4 rebar ) and n = 1 for 5 / 8-inch diameter or # 5 and # 6 rebar .
