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 8-23 as necessary to the above values . Compare to the steel values in table 7 .

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 . For diamond core drilling , except as indicated in note 10 , multiply above values by 0.55 . Diamond core drilling is not permitted for the water-filled or under-water ( submerged ) applications . 10 Diamond core drilling with the Hilti TE-YRT roughening tool is permitted for # 5 , # 6 , # 7 , # 8 , and # 9 rebar in dry and water-saturated concrete . See Table 5 11 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete .
