|Abstract:||The tensile dynamic behaviour of anchors in concrete has been experimentally investigated by employing Hopkinson bar techniques. Dynamic pull-out tests with two anchor size diameters have been performed, concrete cone breakout failure has been predominantly induced, and full force-displacement curves have been obtained. The test results show that properly post-installed anchors can achieve the same load bearing capacity as the cast-in-place ones. It has also been verified that the three different types of anchors tested (with chemical adhesive, undercut, and headed studs) can develop comparable failure loads under similar embedment depths. Test results have demonstrated that force-displacement diagrams for dynamic loading tend in general to lie well above the corresponding static ones, i.e. additional ductility is available. Comparisons with predictions from design formulae have been conducted.|
