Abstract:
Although the influence of rapid loading on the behavior of anchors installed in concrete has been addressed by researchers in various contexts (earthquake, blast, and so on), no study has provided a comprehensive description of the influence of loading rate on anchor load-bearing behavior differentiated by failure mode. This paper integrates previous work on this topic with new experimental work on adhesive anchors, expansion anchors, and torque-controlled adhesive anchors in cracked concrete under rapid tension loading. While this research was performed using loading rates relevant for seismic applications, many of the findings are transferable to other anchorage applications. The findings indicate that tests at rapid load rates are not necessary for the qualification of anchors for seismic applications.
