1 See Section 3.1.8.6 to convert design strength value to ASD value . 2 Hilti KCM-MD Inserts are considered as brittle steel elements 3 Tension values are for the inserts only . The capacity of the threaded rods must be also determined from Table 10 . The design strength of concrete must be obtained from tables 4 to
9 . 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 10 . 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 .
