1 Linear interpolation between embedment depths and masonry compressive strengths is not permitted .
2 Tabular values are for a single anchor located at minimum edge of 1-3 / 4-in ( 2-3 / 4-in for 5 / 8-in diameter ) from edge parallel with masonry course with no additional influence from nearby edges or additional anchors . For designs with the additional influence of nearby edges , a different edge distance , 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 . 5 Tabular shear values are for shear force parallel to the edge parallel with the masonry course . For shear force perpendicular to the edge parallel with the masonry course , multiply design strength values in shear by the following reduction factors : 3 / 8-in and 1 / 2-in . diameter = 0.50 5 / 8-in diameter = 0.46
