1 Linear interpolation between embedment depths and masonry compressive strengths is not permitted .
2 Tabular values are for a single anchor located 2.5-in from centerline of a hollow head joint with no additional influence from nearby edges or additional anchors . For designs with the influence of nearby edges , different distances to a hollow head joint , or additional anchors , use Hilti PROFIS Engineering Design software or perform anchor calculation using design equations from AC01 . 3 Compare masonry tabular values to the steel values in Table 8 . The lesser of the values is to be used for the design . 4 Tabular values are for static loads only . Seismic design is not permitted for uncracked masonry .
