Outline of Final Research Achievements |
A new type of post-tensioned energy dissipating precast concrete frame structure is proposed. The frame includes prestressing force variation suppression 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 effect of the devices on the nonlinear behavior and condition of damage is presented, and the evaluation methods for the structural performance are proposed.
