Bond Strength of Adhesive Post-installed Anchor for Seismically Damaged and Crack-repaired Rc Beam

Year: 2025

Type: article

Abstract: Post-installed anchors are used to repair and strengthen existing concrete structures. Recently, RC structures damaged by earthquakes are used for a long time. Therefore, in this study, we investigated the bond strength of the post-installed anchor bonded to the RC beams before and after shear loading tests, and to crack-repaired RC beam. The bond strength was reduced by about 20 % for Damage II and about 30 % for Damage III compared to Non-Damage. In addition, the bond strength with crack-repair increased by up to 107 % compared to it without crack-repair.
