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 Tables 3A and 3B and threaded rod steel strength values in Table 10 . 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 KCM-MD anchors , calculation of static and seismic concrete strength in shear is not required . See Tables 3A and 3B for shear calculations .
