چکیده انگلیسی
To prevent the large axial prestressing forces that are typically necessary for a post-tensioned precast segmental column, a semi-rigid connection for a precast segmental bridge pier system is proposed. The proposed connection between segments is a hybrid connection containing bonded bar reinforcement that is spliced by bar couplers and shear keys to provide shear resistance between neighboring segments. Unbounded tendons with a small prestressing force can also be included to provide re-centering forces. Two types of connection between each prefabricated element, i.e., a steel dowel shear key and a reinforced concrete (RC) shear key, are proposed and tested. From the experimental results and construction practices of the developed system, the high seismic resistance and the satisfactory constructability of the proposed pier are confirmed. Furthermore, to establish a proper analysis procedure for such a bridge column system, two finite-element models using solid elements and beam elements from the laboratory tests are also generated and both are shown to be appropriate and effective in capturing the seismic behavior of the proposed system.
