Concrete masonry units must be light-, medium- <br />, or normal -weight conforming to ASTM C90. Allowable loads have been calculated using a safety factor of 5. <br />2 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. <br />When using the alternative basic load combinations in the 2009 IBC Section 1605.3.2 that include seismic or wind loads, tabulated allowable loads may be <br />increased, or the alternative basic load combinations may be reduced according to Table 2. For the 2018, 2015 and 2012 IBC, the allowable loads or load <br />combinations must not be adjusted. <br />3 One anchor must be permitted to be installed in each cell of the CMU block. Refer to Figure 3 for an illustration of the anchor location for which the tabulated <br />values are applicable. <br />4 The tabulated edge distance is measured from the anchor centerline to the edge of the CIVIL block as depicted in Figure 3. <br />5 Anchors must be installed into the grouted cell. Anchors are not permitted to be installed in a head joint, flange or web of the concrete masonry unit. <br />6 Linear interpolation of load values between the two tabulated edge distances is permitted, as applicable. <br />Allowable loads must be the lesser of the adjusted masonry or bond values tabulated above and the steel values given in Tables 10 and 11. <br />e Tabulated allowable bond loads must be adjusted for increased base material temperatures in accordance with Figure 1, as applicable. <br />
