1 Linear interpolation between embedment depths and masonry compressive strengths is not permitted . 2 Tabular values are for a single anchor with no influence from nearby edges , hollow head joints , or additional anchors . For designs with the influence of nearby edges , hollow head joints , 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 The maximum embedment for a 8-in CMU block is 6-3 / 4-in . The maximum embedment for a 10-in CMU block is 8-in . The maximum embedment for a 12-in CMU block is 10-in . 5 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 0.82 . 6 Tabular values are for dry masonry conditions . For water saturated masonry conditions , multiply design strength values by α sat
# 3 rebar - α sat = 1.00
# 4 rebar - α sat = 0.93
# 5 rebar - α sat = 0.79
# 6 rebar - α sat
= 0.65 7 Tabular values are for static loads only . Seismic design is not permitted for uncracked masonry . 8 Tabular values are for short term loads only . For sustained loads including overhead use , see Section 3.0 .
