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 3 / 4-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 AC58 . 3 Compare masonry tabular values to the steel values in the Appendix . The lesser of the values is to be used for the design . 4 Data is for Temperature Range A : Maximum short term temperature = 130 ° F ( 55 ° C ) | Maximum long term temperature = 110 ° F ( 43 ° C ).
For Temperature Range B : Maximum short term temperature = 176 ° F ( 80 ° C ) | Maximum long term temperature = 110 ° F ( 43 ° C ), multiply design strength values values by 0.91 . 5 Tabular values are for dry masonry conditions . For water saturated masonry conditions , multiply design strength values by :
1 / 2-in diameter - α sat
= 0.84 5 / 8-in and 3 / 4-in diameter - α sat
= 1.00 6 Tabular values are for static loads only . Seismic design is not permitted for uncracked masonry . 7 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 : 1 / 2-in and 5 / 8-in . diameter = 0.50 3 / 4-in diameter = 0.46
8 Tabular values are for short term loads only . For sustained loads including overhead use , see Section 3.0 .
