Abstract:Based on the concept of earthquake resilience design and incorporated the key technology of precast structures, a self-centering precast bridge column (SPBC) with exterior replaceable energy dissipation devices (EDDs) was developed. Quasi-static lateral cyclic tests of two groups of scaled SPBC models were carried out to investigate and analyze its seismic behavior. The force-displacement hysteresis behavior, skeleton curve, energy dissipation capacity, tension force of prestressing tendons, residual displacement, joint opening, compression zone height at pier bottom were analyzed. The results show that the exterior EDDs adopted in the developed columns have good replaceability and energy dissipation capacity, and the seismic performance of models before and after the replacement of EDDs is basically the same. The hysteretic curves show obvious "flag" type behavior. Smaller residual displacement and good self-centering ability were produced for the SPBC models. With the increase of loading displacement, the tension forces of prestressing tendons in SPBC models increased linearly. The prestress loss was reduced after the EDDs were replaced. The exterior steel jacket at the column base can effectively restrain the local concrete damage, and the steel jacket had no damage such as local exterior bulge.
