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 Anchors may be installed in any location in the face of the masonry wall including cell , web , and mortar joints . Anchors are limited to one per masonry cell . 3 Linear interpolation of load values between minimum spacing ( s min
) and critical spacing ( s cr ) and between minimum edge distance ( c min
) and critical edge distance ( c cr
) is permitted . 4 Concrete masonry thickness must be equal to or greater than 1.5 times the anchor embedment depth . EXCEPTION : the 5 / 8-inch- and the 3 / 4-inch diameter anchors ( No . 5 and No . 6 bars ) may be installed in minimum nominally 8-inch thick concrete masonry .
5 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 When using the alternative basic load combinations in IBC Section 1605.3.2 that include seismic or wind loads , tabulated allowable loads may be increased by 33-1 / 3 percent , or the alternative basic load combinations may be reduced by a factor of 0.75 . 6 Allowable loads must be the lesser of the adjusted masonry or bond tabulated values and the steel values given in tables 102 and 103 . 7 Tabulated allowable loads shall be adjusted for increased base material temperatures in accordance with figure 14 . 8 For combined loading : ( T applied
/ T allowable ) + ( V applied
/ V allowable ) ≤ 1
9 The critical spacing , s cr , is the anchor spacing where full load values may be used . The minimum spacing , s min
, is the minimum anchor spacing for which values are available and installation is recommended . Spacing is measured from the center of one anchor to the center of an adjacent anchor . 10 The critical edge distance , c cr
, is the edge distance where full load values may be used . The minimum edge distance , c min , is the minimum edge distance for which values are available and installation is recommended . Edge distance is measured from the center of the anchor to the closest edge . 11 Embedment depth is measured from the outside face of the concrete masonry unit . 12 Load reduction factors are multiplicative , both spacing and edge distance load reduction factors must be considered . Load values for anchors installed at less than s cr and c cr must be multiplied by the appropriate load reduction factor based on actual edge distance ( c ) and spacing ( s ).
