| Accelerated Bridge Construction (ABC) in seismic regions is currently a research focal point. ABC is bridge construction that uses innovative planning, design, materials, and construction methods in a safe and cost-effective manner to reduce the onsite construction time that occurs when building new bridges or replacing and rehabilitating existing bridges. The research at Idaho State University included large scale testing of an experimental cantilever precast column and a cast-in-place column. The precast column design incorporated a hollow structural steel member into the column to footing connection. The test specimen is tested to failure following the ACI guide for testing reinforced concrete structural elements under slowly applied simulated seismic loads. The testing procedure is accomplished using a uniaxial quasi-static loading protocol. Results revealed that the experimental column achieved a higher drift ratio, resisted greater force, and dissipated more energy compared to a traditional cast-in-place column.
