Abstract: This paper presents an update to the approach proposed by Gaudreau et al. (2004) for assessing the performance of tendon support systems subjected to dynamic loading. Initially, the updated approach was developed subsequent to the quasi-static and impact pull-out testing data assembled during the modified cone bolt (MCB) prototype tendon support validation. The technique has subsequently been used to estimate the displacement of tendon support systems when subjected to dynamic loading, using experimental data from the tendon’s response to quasi-static loading and its material properties. The proposed displacement evaluation method provides a means of calculating the maximum capacity range of tendons for rockburst support design.
