1 See section 3.1.8 of PTG (Ed. 17) for explanation on development of load values.
2 See section 3.1.8.6 of PTG (Ed. 17) 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 23-30 as necessary to the above values. Compare to the steel values in table 22.
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).
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signicantperiodsoftime.
6 Tabular values are for dry concrete conditions. For water saturated concrete multiply design strength by 0.85.
7 Tabular values are for short term loads only. For sustained loads including overhead use, see section 3.1.8.8 of PTG (Ed. 17).
