Abstract

<p>In this study, a method was developed to assess the results of bond strength tests with the aim of mitigating the degradation of long-term performance in post-installed anchors. This degradation can occur due to the absence of an upper limit on maximum displacement at bond strength and the allowance for significant creep deformation. The study confirmed that utilizing a judgment equation based on linear approximation and tri-linear curves can evaluate the test results that are allowed, necessary to reassess, potentially suitable for use, and requiring disposal.</p>
