This study provides insights into the performance of post-installed anchors in deteriorated concrete. Post-installed anchors are commonly used in existing reinforced concrete buildings for seismic retrofitting and equipment installation. However, studies on the performance of these anchors in deteriorated concrete are limited. This study focuses on the tensile resistance performance of post- installed anchors in frost-damaged concrete. Nine test specimens were fabricated with varying degrees of frost damage deterioration. The results showed that as frost damage increased, the tensile strength decreased, particularly at a 60% deterioration level. Observations of concrete failure confirmed that the angle of the cone-failure surface decreased with increasing deterioration levels. A finite element model was developed to analyze the damage state inside the member, considering the reduction in the material properties of the concrete. The analysis revealed variations in the crack angles and initiation times depending on the degree of frost damage deterioration.
