Design Guidelines for Post-Installed Mechanical Anchors in Concrete Subjected to Impact Loads
Current United States design provisions for post-installed mechanical anchors are typically tailored toward conventional static and dynamic load regimes, such as seismic and wind loads. In fact, the dynamic behavior of post-installed anchors in reinforced concrete is primarily based on seismic loading effects. Yet, dynamic loads that produce extremely short duration impact, such as air-blast, are not addressed in design criteria, including anchorage to concrete. Usually this is not an issue as most structures are not designed to withstand these forces; however, when blast applications are considered, there is no clear method to determine how these anchors will perform. With little research on the behavior of anchor bolts under impact loads, in comparison to other long term cyclical loadings, properly designing concrete anchorage to meet these demands is difficult.
