Abstract:

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 experimental and analytical investigation of a new precast pier system for applications in seismic zones. The precast pier system uses hollow structural tubes filled with concrete in plastic hinge locations. Extensive testing on precast cantilever and bent piers was conducted to investigate seismic performance under quasi-static cyclic loads. Results were compared against benchmark cast-in-place specimens. Testing showed superior performance of the precast pier compared to cast-in-place. Limited analytical and some parametric studies are carried out to assist the designer in computational work. Furthermore, flexural analysis, interaction diagrams, design and detailing considerations, construction and assembly technology, limitations, inspection, and some proposed post-earthquake repair methodologies are presented.
