New Strategies for Maintaining Post-Seismic Operations of Lifeline Corridors
This project furthered the development of three strategies that could positively impact maintaining post-seismic operations of lifeline corridors. In Year 1, most of the focus was on the development of the three individual strategies. In Year 2, a follow-up project will include more formal assessments of the situation in which ...
SSI-Bridge: Soil-Bridge Interaction During Long-Duration Earthquake Motions
The seismic response of a complete soil-bridge system during shallow, crustal and subduction zone earthquakes is the topic of this report. Specifically, the effects of earthquake duration on the seismic performance of soil-bridge systems are examined. This topic is important, because many bridges worldwide are located in ...
SSI-Bridge 2: Soil-Bridge Interaction During Long-Duration Earthquake Motions
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 ...
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 ...
