1 See Section 3.1.8 for explanation on development of load values . 2 See Section 3.1.8 to convert design strength value to ASD value . 3 Linear interpolation between embedment depths and concrete compressive strengths is not permitted .
4 Apply spacing , edge distance , and concrete thickness factors in tables 61-70 as necessary to the above values . Compare to the steel values in table 53 . The lesser of the values is to be used for the design .
5 Data is for temperature range A : Max . short term temperature = 130 ° F ( 55 ° C ), max . long term temperature = 110 ° F ( 43 ° C ). For temperature range B : Max . short term temperature = 176 ° F ( 80 ° C ), max . long term temperature = 110 ° F ( 43 ° C ) multiply above values by 0.69 .
Short term elevated concrete temperatures are those that occur over brief intervals , e . g ., as a result of diurnal cycling . Long term concrete temperatures are roughly constant over significant periods of time .
6 Tabular values are for dry concrete and water-saturated concrete conditions . For water-filled drilled holes multiply design strength by 0.51 . For submerged ( under water ) applications multiply design strength by 0.45 . 7 Tabular values are for short term loads only . For sustained loads including overhead use , see Section 3.1.8 . 8 Tabular values are for normal-weight concrete only . For lightweight concrete multiply design strength by λ a as follows :
For sand-lightweight , λ a = 0.51 . For all-lightweight , λ a
= 0.45 . 9 Tabular values are for holes drilled in concrete with carbide tipped hammer drill bit . Diamond core drilling is not permitted in cracked concrete conditions except as indicated in note 10 .
10 Diamond core drilling with Hilti TE-YRT roughening tool is permitted for 15M and 20M diameter anchors for dry and water-saturated concrete conditions . See Table 60 .
11 Tabular values are for static loads only . For seismic loads , multiply cracked concrete tabular values by α seis = 0.68 . See section 3.1.8 for additional information on seismic applications .
