ACI Fall 2025 Convention, Baltimore, MD

Abstract:

This study presents the design, construction, and shaking table testing of a two-column bridge bent developed for accelerated bridge construction with low-seismic damage objectives. The system incorporates precast post-tensioned columns connected to precast foundation and bent caps, with each column consisting of reinforced concrete cast inside a cylindrical steel shell that serves as formwork, confinement, and shear reinforcement. The steel shell is detailed to promote a rocking interface that concentrates seismic deformation demands at the column ends. Precast foundation and cap elements contain corrugated-metal-duct lined sockets, allowing on-site grouting to form the joints. A 35%-scale bent was constructed and subjected to combined horizontal and vertical ground motion inputs on a shaking table. Testing confirmed that seismic rotations concentrated at the column ends as intended, the bent exhibited excellent recentering capability, and observed damage was minimal, thus, validating the design objectives.
