Tests of Hilti Kwik-Bolts in Coredrilled Holes Issue (Cygna RIL No. 7)
Coredrilled holes may be slightly larger in diameter than holes drilled with Hilti masonry carbide bits, resulting in a potential reduction in pullout capacity.
Resolution A testing program has been completed by SWEC to - validate the pullout capacity of Hilti anchors installed in coredrilled holes.

Tests of Hilti Kwik-Bolts in Coredrilled Holes '(Cont.)
Test Program Test slab poured using CPSES 4,000 psi concrete as specified in Specification 2323-CS-9, Revision 6.
Hilti expansion anchors were installed in test slab per Specification 2323-SS-30, Revision 3.
Tension tests were performed per ASTM E-488.
Specimens 3/4 in. Hilti Kwik Bolts 1 in. Hilti Kwik Bolts 1 in. Hilti Super Kwik Bolts 1 1/4 in. Hilti Kwik Bolts Test results were adjusted downward to account for actual c,oncrete compressive strength of 5230 psi.
Test report is No.

4 Tests of Richmond Inserts with Partial Bolt Engagements Issue In certain instances, bolts were determined to be installed in Richmond inserts with short thread engagements.
Resolution A testing program was performed to determine the capacities of Richmond inserts with a range of bolt engagements and load combinations. The results of the tests were incorporated into the Design Basis Document DBD-CS-015.
Installations that utilized Richmond inserts have been design validated based on the design criteria specified in the Design Basis Document.
Test Program Tests were performed on unused, in-plant, 1-in. and 1 1/2-in. Richmond inserts.
Shear, tension, and shear / tension interaction tests were performed for.
a range of bolt engagements.
Tests were performed in accordance with ASTM E-488, as applicable.
