Behavior of Post-Installed Anchors Tested by Stepwise Increasing Cyclic Crack Protocols
The American Concrete Institute (ACI) standards for qualification of post-installed concrete anchors (ACI 355.2 and ACI 355.4) include a nonseismic crack movement test characterized by a large number of small-amplitude crack cycles. This paper investigates anchor response to a new stepwise-increasing cyclic crack protocol with a number of crack cycles and crack widths developed specifically to represent conditions anticipated during earthquakes. This new protocol formed the basis of the seismic qualification for post-installed anchors recently amended for use in European approval guidelines. The load-displacement behavior of common post-installed anchors subjected to the new seismic protocol is illustrated, showing the distinctly different responses of various anchor types. Some anchors exhibit significant displacements and reduced residual load capacities or even failure during crack cycling.
