Note (General): This research investigates the bond and fracture characteristics　of PC tendons embedded in grouting mortar from a quasi-static　and dynamic perspective. Investigation of the interaction between smooth tendons and surrounding mortar is crucial for　accurate estimation of bond performance and degradation. To this　extent damage in tendons is investigated from　experimental and　numerical analysis. Additionally, damage modeling parameters are　proposed and numerical analysis results are verified using image　analysis. Furthermore, through pullout experimental　investigation bond stress-slip performance is observed and analytical bond model is proposed. Good agreement is noted between experimental results and proposed model. Using finite element analysis based on proposed model, accurate replication of pull-out experiment is achieved for different pullout rates and grout material strength properties.
