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 19 – 20 as necessary to the above values . Compare to the steel values in table 30 .

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 value by 0.93 . For temperature range C : Max . short term temperature = 248 ° F ( 120 ° C ), max . long term temperature = 162 ° F ( 72 ° C ) multiply above value by 0.58 . 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 or water saturated concrete conditions . 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 horizontal and vertical downward direction only . For overhead ( vertical up ) installation , tabular values must be multiplied by 0.70 . 10 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete . For seismic loads , multiply cracked concrete tabular values in tension and shear by

α _seis

= 0.75 . See section 3.1.8 for additional information on seismic applications .
