1 See section 3.1.8 for explanation on development of load values . | |||||||||
2 See section 3.1.8 to convert design strength ( factored resistance ) 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 42 - 55 as necessary to the above values . Compare to the steel values in table 41 . | |||||||||
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 value by 0.42 . | |||||||||
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 ( factored resistance ) 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 : | |||||||||
3 / 8-in diameter - α seis = 0.66 |
1 / 2-in , 5 / 8-in , and 1-1 / 4-in diameter - α seis = 0.74 |
||||||||
3 / 4-in and 7 / 8-in diameter - α seis = 0.75 |
1-in diameter - α seis = 0.71 |
||||||||
See section 3.1.8 for additional information on seismic applications . | |||||||||
