<br />(The following footnotes apply to both Tables 8A and 813)
<br />All values are for anchors installed in hollow brick masonry with minimum masonry strength of 3000 psi. Hollow brick units must be in conformance with ASTM
<br />C652. Allowable loads have been calculated using a safety factor of 5.
<br />2 Tabulated embedment depth is limited by the length of the plastic HIT -SC screens.
<br />3 Anchors must be installed in the face of the hollow brick masonry wall.
<br />4 Tabulated values are for the anchor installed in the center of the hollow brick, mortar joints, flanges, or cell web (all wall face locations permitted).
<br />5 The critical spacing, sc,, is the anchor spacing where full load values in the table may be used. The minimum spacing, s-, is the minimum anchor spacing for
<br />which values are available and installation is recommended. Spacing is measured from the center of one anchor to the center of an adjacent anchor.
<br />6 The critical edge distance, Cyr, is the edge distance where full load values in the table may be used. The minimum edge distance, Cmin, is the minimum edge
<br />distance for which values are available and installation is permitted. Edge distance is measured from the center of the anchor to the closest edge.
<br />Load values for anchors installed at less than scr and Cyr must be multiplied by the appropriate load reduction factor based on actual edge distance (c) or spacing
<br />(s)
<br />8 Anchors are not recognized for resisting earthquake forces. When using the basic load combinations in accordance with IBC Section 1605.3.1, or the alternative
<br />basic load combinations in IBC Section 1605.3.2, tabulated allowable loads must not be increased for wind loading.
<br />s Allowable loads must be the lesser of the adjusted masonry or bond values tabulated above and the steel values given in Table 10.
<br />10 Tabulated allowable bond loads must be adjusted for increased base material temperatures in accordance with Figure 1, as applicable.

<br />4 Tabulated values are for one anchor installed in the center of the hollow brick, mortar joints, flanges, or cell web (all wall face locations
<br />permitted).
<br />5 One anchor must be permitted to be installed in each brick. Two anchors installed in adjacent bricks may be spaced as close as 8 inches apart
<br />with no load reduction.
<br />6 The critical edge distance, cc,, is the edge distance where full load values in the table may be used. The minimum edge distance, Cmin is the
<br />minimum edge distance for which values are available and installation is permitted. Edge distance is measured from the center of the anchor to
<br />the closest edge.
<br />7Anchors are not recognized for resisting earthquake forces. When using the basic load combinations in accordance with IBC Section 1605.3.1,
