摘要：

Although post-installed anchors are used for seismic reinforcement and installation of equipment, there is concern that the anchorage performance of anchor bolts anchored to base concrete with a surface layer that has been subjected to frost-damage will deteriorate. In this study, pull-out tests of post-installed anchors anchored to a specimen with a simulated surface layer subjected to frost-damaged concrete were conducted to investigate cone fracture of concrete. The results showed that the tensile strength of the deteriorated specimens was lower than that of the non-damaged specimens. © 2024 Architectural Institute of Japan. All rights reserved.
