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 10 - 17 as necessary to the above values . Compare to the steel values in table 62 . 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 1.00 . For temperature range C : Max . short term temperature = 248 ° F ( 120 ° C ), max . long term temperature | |||||||||
= 162 ° F ( 72 ° C ) multiply above values by 0.90 . 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 . | |||||||||
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 la as follows : For sand-lightweight , λ a = 0.51 . | |||||||||
|
For all-lightweight , λ a
= 0.45 .
| |||||||||
9 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 only by the following | |||||||||
reduction factors : | |||||||||
3 / 8-in diameter - α N , seis = 0.705 |
1 / 2-in to 3 / 4-in diameter - α N , seis = 0.75 |
