1 See Section 3.1.8.6 to convert design strength value to ASD value . 2 Linear interpolation between concrete compressive strengths is not permitted . 3 Tabular value is for one anchor per flute . Minimum spacing along the length of the flute is 3 x h _ef

( effective embedment ).

4 Tabular values are for normal weight or sand-light weight concrete . 5 No additional reduction factors for spacing or edge distance need to be applied . 6 Compare tabular value to the insert steel strength values in Compare tabular value to the insert steel strength values in Table 17 and threaded rod steel strength values in Table 27 .

The lesser of the values is to be used for the design . 7 Tabular values are for static loads only . For seismic tension loads , multiply cracked concrete tabular values in tension by α _N _, _seis

= 0.75 . See PTG ED . 19 , Section 3.1.8.7 for additional information on seismic applications . 8 For Hilti KCC-MD anchors , calculation of static and seismic concrete strength in shear is not required . See Table 20 for shear calculations .
