<br /> 1 Anchors may be placed in the upper or lower flute of the steel deck profile provided the minimum concrete cover above the drilled hole is
<br /> satisfied.Anchors in the lower flute may be installed with a maximum 1-inch offset in either direction from the center of the flute.The offset
<br /> distance may be increased proportionally for profiles with lower flute widths greater than those shown provided the minimum lower flute edge
<br /> distance is also satisfied.

<br /> 1 See PTG Ed.19 Section 3.1.8 to convert design strength value to ASD value.
<br /> 2 Linear interpolation between embedment depths and concrete compressive strengths is not permitted.
<br /> 3 Apply spacing,edge distance,and concrete thickness factors in tables 20 and 21 as necessary.Compare to the steel values in table 4.The lesser of the values
<br /> is to be used for the design.
<br /> 4 Tabular values are for normal weight concrete only. For lightweight concrete multiply design strength by Aa as follows:
<br /> for sand-lightweight,A.=0.68;for all-lightweight,k=0.60
<br /> 5 Tabular values are for static loads only.Seismic design is not permitted for uncracked concrete.For seismic tension loads,multiply cracked concrete tabular val-
<br /> ues in tension by the following reduction factors:
<br /> 1/4-inch diameter-a...,,=0.60
<br /> 3/8-inch diameter-a,,5,,,=0.75.
<br /> No reduction needed for seismic shear.See PTG Ed.19 Section 3.1.8 for additional information on seismic applications.
