Concrete masonry units must be light-, medium, <br />normal -weight conforming to ASTM C90. 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 CMU masonry wall. A maximum of two anchors may be installed in a single cell of the hollow CMU block. <br />4 Tabulated values are for one anchor installed in the cell of the hollow CMU. Installation in other locations of the hollow CMU (mortar joints, flange, or cell web) is <br />not permitted. <br />' The minimum spacing, smin, for which values are available and installation is permitted is 4 inches. Two anchors installed in adjacent cells may be spaced as <br />close as 4 inches apart with no reduction in tension or shear capacity. Two anchors installed in the same cell can be spaced as dose as 4 inches apart with no <br />reduction in shear capacity. For two anchors installed in the same cell spaced as close as 4 inches apart, the 3/8-inch and''Y2-inch diameter HIT -IC inserts <br />require a 20% reduction in the tension capacity, and the'/,6-inch diameter HIT -IC insert requires no reduction in tension capacity. <br />6 The critical edge distance, Ccr, 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 />7 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 />' Allowable loads must be the lesser of the adjusted masonry or bond values tabulated above and the steel values given in Table 10. <br />9 Tabulated allowable bond loads must be adjusted for increased base material temperatures in accordance with Figure 1, as applicable. <br />
