| Research Abstract |
A new type of unbonded post-tensioned precast concrete frame structure is proposed. The frame includes energy dissipating devices connected directly to post-tensioning tendons in anchorage zone. To investigate and validate the structural performance of the frame, analytical studies are conducted using several types of numerical models. The analytical results obtained from the numerical models show the effect of energy dissipation devices on the behavior of the frame, the condition of damage in the beams, and the ultimate state of the behavior at the beam-column interface of the connections.
