Abstract:

Accelerated bridge construction (ABC) using precast concrete bents has substantial potential to improve construction time and seismic performance in earthquake-prone regions. This study investigates the seismic performance of hybrid self-centering bridge bents that employ unbonded post-tensioning (PT) bars for self-centering and replaceable stretch length anchors (SLAs) as external energy-dissipation devices. Experimental cyclic loading tests were performed on a 42% scale, two-column bridge bent to assess its self-centering capability and hysteretic energy dissipation. The study included four test configurations: two with combined PT bars and SLAs and two with PT bars only, the variables included shear key details at the footings and cap beam.
