The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...

Cross-laminated timber engineering : improvement and application

Creator:: Kramer, Anthonie
Abstract:: The development of cross-laminated timber (CLT) panel technology has opened up new opportunities for wood in tall buildings. Several characteristics including seismic performance and speed of construction have raised interest among designers. As CLT gains acceptance in the industry, alternative structural solutions need to be investigated to improve performance of...

The character and biological treatability of log pond waters

Creator:: Hoffbuhr, Jack Wayne
Abstract:: A study was conducted to determine the chemical nature and the biological treatability of log pond water. Various analyses including total solids, volatile solids, suspended solids, dissolved oxygen, pH, COD, BOD₅, BOD₂₀, total Kjeldahl nitrogen, nitrate nitrogen, phosphate, and PBI were performed on water samples from each of the four...

Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

Creator:: Lathrop Eve D.
Abstract:: The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...

Relationships between seasonal suspended sediment behavior and reservoir turbidity

Creator:: Conner, Dan Alan
Abstract:: The causes of turbidity in impounded and released reservoir water are studied. Seven Willamette Basin reservoirs are compared to isolate watershed and reservoir characteristics which produce variations in turbidity. Of the seven, Hills Creek Reservoir is examined in detail. Particular features of the basin and impoundment are studied to isolate...

Light-frame versus timber frame : a study in quantifying the differences

Creator:: Malone, Brian P.
Abstract:: The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

Wave modeling at the mouth of the Columbia River

Creator:: Kassem, Sarah
Abstract:: As the second largest river in the U.S., the entrance to the Columbia River is home to some of the most extreme wave conditions on the Pacific Coast. Winter storms commonly generate waves 6-8 m in height, which in combination with strong tidal currents, can produce dangerous navigation conditions. To...

Full-Scale Experimental Investigation of the Seismic Capacity of Reinforced Concrete Column-Footing Specimens Retrofitted with Titanium Alloy Bars Considering Effects of Soil-Structure Interaction on Vintage and Retrofitted Column-Footing Specimens

Creator:: McGinn, Logan
Abstract:: Reinforced concrete (RC) column-footing substructures are widely used to support bridges along critical transportation corridors in Oregon. Those built prior to 1971 were typically designed to resist only gravity loads. Therefore, they are vulnerable to damage or collapse during strong ground shaking. To prevent collapse, seismic retrofits have been developed...

Nonlinear dynamic analysis of cable and membrane structures

Creator:: Lo, Alain
Abstract:: The nonlinear dynamic analysis of cable and membrane structures is presented in this study. Attention is given to the nonlinearities arising from large displacements, from nonlinear stress-strain relationships and from nonconservative loadings. The finite element method is used to model the cables and membranes. Curvilinear geometries of the elements are...

Modular Cross Laminated Timber Structures Using Underutilized Ponderosa Pine

Creator:: Bhandari, Sujit
Abstract:: Conflicts and disasters displace millions of populations worldwide. There is a need for rapid and affordable housing to cater to the needs of the displaced and unhoused population. Experience from previous post-disaster responses shows that temporary housing should be rapidly deployable, planned for months to years, and should be environmentally...
