Abstract:
Undercut anchors reliably transfer high static and cyclic loads into concrete by a robust mechanical interlock. To evaluate performance of post-installed anchors, the design strength was compared for three types of mechanical anchors (undercut anchor, screw anchor, and expansion anchor) and one adhesive anchor embedded in concrete and the load-displacement performance was compared for an undercut and adhesive anchor.
