The discussion is based on an analysis performed using analytical models comprised of a prestressed concrete frame element with a bond slip in the unbonded prestressing tendon, and a beam-column joint element with a bond slip. The accuracy of the analytical models is illustrated by comparing the behavior of the models with the results of previous experiments conducted on beam-to-column subassemblies with hybrid post-tensioned connections. Following this, an analytical parametric study is presented that investigates the effects of variations in the connection details on the behavior of the subassemblies. The results of this study indicate that the energy dissipation of these subassemblies can be estimated from the amount of bonded reinforcing steel bars, and that the self-centering capability can be evaluated from the ratio of the level of initial prestressing force to the amount of bonded reinforcing steel bars.
