1 Design information in this table is taken from ICC-ES ESR-4145 , Table 4B , and converted for use with CSA A23.3 ( R2014 ) Annex D . 2 The carbon steel KCM-MD is considered a brittle steel element as defined by CSA A23.3 ( R2014 ) Annex D section D . 2 . 3 Tension values are for the inserts only . The capacity of the threaded rods must be also determined from Table 18 . The design strength of concrete must be obtained from tables 12 to 17 . Compare the tension values of threaded rod , inserts , and concrete . The lesser of the values is to be used for the design .
4 Shear values are for the inserts only . The capacity of the threaded rods must be also determined from Table 18 . The calculation of concrete shear strength is not required . Compare the shear values of threaded rod and inserts . The lesser of the values is to be used for the design strength of the anchor in shear .
5 Only threaded rod ASTM A193 Grade B7 , ASTM A325 , or ASTM F1554 Grade 105 is permitted to be used for the applications resisting shear , seismic shear , or seismic tension loads .
