ANCHORAGE PERFORMANCE OF LONG ADHESIVE ANCHORS IN ELAST-PLASTIC REGION

In recent years, there has been a growing trend to use adhesive anchors with long anchorage lengths as main reinforcement in the expansion and renovation of existing buildings and in new buildings. Therefore, it is necessary to understand the deformation performance and anchorage performance of anchors in the plastic region, which have not been studied in adhesive anchors until now. In this study, we clarified the deformation capacity and bond performance in the plastic region after yielding of long adhesive anchors. Furthermore, we conducted a finite element analysis of pull-out tests of long adhesive anchors.
