1 See Section 2.4 for explanation on development of load values.
2 See Section 2.4.4 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 13 - 17 as necessary. Compare to the steel values in table 12.
The lesser of the values is to be used for the design.
5 Data is for temperature range A: Max. short term temperature = 104° F (40° C), max. long term temperature = 75° F (24° C).
For temperature range B: Max. short term temperature = 176° F (80° C), max. long term temperature = 122° F (50° C) multiply above value by 0.83.
For temperature range C: Max. short term temperature = 248° F (120° C), max. long term temperature = 162° F (72° C) multiply above value by 0.48.
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 2.4.5.
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.
