Effect of Loading Rate on the Bonding Strength between Rebar and Concrete
In this study, the effect of loading rate on the bonding strength between rebar and concrete substrate is investigated through pull-out test on 24 concrete cylinders. The load capacity, shear deformation and fracture characteristics of the interface are examined carefully. It is found that with the increase of loading rate, the load capacity increases correspondingly and their relationship can be characterized with a semi-logarithm equation. The load-deflection curves expand with the increase of loading rate, which is an indication of a gradually increasing energy absorption capacity with the increase of loading rate. Generally, with higher loading rate, more energy is dissipated.
