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 ...

Subduction zone earthquakes are characterized by their large magnitudes, which produce many cycles of strong ground shaking, and thus, long-duration earthquake motions. The Pacific Northwest is prone to subduction zone earthquake motions. Furthermore, many of the coastal bridges in the Pacific Northwest, which will be affected ...
