Behavior of Drilled Shafts with High-Strength Reinforcement and Casing
Drilled shafts provide significant geotechnical resistance for support of highway bridges, and are used throughout the States of Oregon and Washington to meet their structural foundation requirements. Due to changes in construction methods and poor near-surface soils, the use of permanent steel casing for drilled shaft ...
Competitive State-of-the-Art Structural Engineering
The University of Alaska Fairbanks (UAF) steel bridge team had an exceptional year, largely due to the chemistry of the team and to financial backing at all levels. The team won the regional competition and placed ninth at the national competition. In addition to competing with other universities, the UAF steel bridge team ...
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 ...
