High-Performance Bridge Systems for Lifeline Corridors in the Pacific Northwest

This report contributes to the development of three key strategies for increasing the seismic resilience of bridges, accelerating their construction, extending their lifespan, and decreasing life-cycle costs. The strategies considered were (1) precasting reinforced concrete columns, (2) constructing columns with concrete filled steel tubes (CFSTs), and (3) constructing columns with higher-strength steel (GR 80). The precast column strategy was furthered by conducting test of precast column to cast-in-place drilled shaft connections and developing a strut-and-tie model to proportion such connections. The strategy of using CFSTs was furthered by conducting tests of a variety of connections, which then provided the basis for design recommendations. The effect on seismic performance of using GR 80 steel was evaluated by performing four tests of columns and numerous material tests.
