INFLUENCE OF CRACK CYCLING TEST ON PULL-OUT BEHAVIOR OF POST-INSTALLED MECHANICAL ANCHORS

Abstract

In this study, the influence of crack and crack cycling on the pull-out behavior of post-installed mechanical anchors was investigated. The results demonstrated that the pull-out load of anchors decreases under cracked conditions compared to uncracked conditions. While the pull-out behavior can be evaluated under conditions with a constant crack width, under crack cycling conditions, excessive displacement may occur, making it impossible to measure the pull-out test in some cases. Moreover, it was clarified that even anchors classified as the same type of exhibit different pull-out behaviors when subjected to crack cycling.
