( 2.0) 1 Tabular values are for a single anchor with no influence from nearby edges or additional anchors. For designs with
the influence of nearby edges or additional anchors, use Hilti PROFIS Engineering Design software or perform anchor calculation using design equations from AC58. 2 Compare masonry tabular values to the steel values in the Appendix. The lesser of the values is to be used for the design. 3 LFRD load capacities based on evaluation in accordance with AC58 4 Data is for Maximum short-term temperature = 176 ° F( 80 ° C) | Maximum long-term temperature = 110 ° F( 43 ° C). 5 Tabular values are for dry masonry conditions. For water saturated masonry conditions, multiply design strength values by:
α sat, 1 / 4-in, 5 / 16-in, 3 / 8-in and 1 / 2-in diameter- α sat = 1.00 6 Tabular values are for static loads only. Seismic design is not permitted. 7 Tabular values are for short term loads only. For sustained loads including overhead use, see Section 3.0 and multiply
design strength values in tension and shear by 0.90.
