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 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 by 0.62. 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 and 3 / 8-in diameter- α sat = 0.48 1 / 2-in diameter- α sat = 0.71 6 Tabular values are for static loads only. Seismic design is not permitted.
