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 71 - 80 as necessary to the above values . Compare to the steel values in table 66 .
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 ). For temperature range C : Max . short term temperature = 248 ° F ( 120 ° C ), max . long term temperature = 162 ° F ( 72 ° C ) multiply above values by 0.82 . 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 and water saturated concrete conditions . For water-filled concrete multiply design strength ( factored resistance ) by 0.73 . 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 static loads only . For seismic loads , multiply cracked concrete tabular values in tension and shear by the following reduction factors :
10M to 20M - α seis = 0.60 , 25M - α seis
= 0.64 , 30M - α seis
= 0.73 See section 3.1.8 for additional information on seismic applications .
