Dynamic behavior of metal-plate-connected wood truss joints

Creator:: Kent, Scott M.
Abstract:: The objectives of this research were to evaluate the behavior of actual metal-plate-connected (MPC) tension-splice and heel wood truss joints under seismic loads from the Northridge earthquake (tension-splice joints only) and under loads from a large artificial earthquake (1.0 g's and 0.67 g's maximum horizontal and vertical accelerations, respectively). A...

The effect of biological deterioration on the performance of nailed oriented strand board sheathing to Douglas-fir framing member connections

Creator:: Kent, Scott M.
Abstract:: Service life prediction models for light-framed wood structures require an extensive quantity of empirical data on deterioration pathologies for the numerous structural components, as well as mechanistic approaches to determine their capacity at various levels of deterioration. The data and models presented in this study satisfy a portion of the...

The link between amphibole aluminum content and reaction rim mineralogy

Creator:: Ellingwood, Ross T.
Abstract:: During volcanic eruptions ascending magma undergoes decompression, resulting in a decrease of dissolved H2O. This creates unstable conditions for the hydrous mineral amphibole. As a result a reaction rim forms from anhydrous minerals such as pyroxene, plagioclase, and Fe-Ti oxides (Rutherford and Hill, 1993). There have been numerous studies done...

Exploring Volcano-Tectonic Connections in Cascadia – Temporal Linkages between Tephra Deposition and Megathrust Earthquakes

Creator:: Gutierrez, Joel C.
Abstract:: Explosively erupting volcanoes and megathrust earthquakes (Mw 8+ magnitude) occur at subduction zones and adjacent volcanic arcs. Volcanic eruptions are observed occurring close in time to megathrust earthquakes in the historical record from at least the 18th century CE to present in locations globally, including Japan in 1707 CE (Chesley...

Impacts of multispecies parasitism on coho salmon (Oncorhynchus kisutch) in Oregon

Creator:: Ferguson, Jayde A.
Abstract:: Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...

Chemical compositions of amphiboles found in veins and hosts rocks of Cretaceous plutons of the Northern Cascades

Creator:: George, Austin
Abstract:: The origin of hornblendite and other mafic mineral-rich veins found in Cretaceous plutonic rocks from the Northern Cascades is currently not well known. This study seeks to investigate the possible relationship between host plutonic rocks and hornblendite and pyroxene-rich veins by comparing the chemical compositions and petrographic features between the...

Timing of Volcanism in Central Oregon: Dating Tam McArthur Rim Volcano

Creator:: Landoni, Katherine G.
Abstract:: The Tam McArthur Rim is a volcanic center located within the Tumalo Volcanic Field (TVF), approximately 25 km west of Bend, OR. The rim comprises of shallowly dipping bedded sequences of intermediate and silicic flows with minor tephra interbedding capped by a rhyodacite dome. Glacial activity has exposed significant portions...

Controls on eruption style and magma compositions at Mount Hood, Oregon

Creator:: Koleszar, Alison M.
Abstract:: This study is an effort to characterize the magma sources, plumbing system, and eruptive behavior of Mount Hood, a low-explosivity recharge-dominated volcano in the Oregon Cascades. The three manuscripts in this dissertation make use of melt inclusion data, phenocryst compositions, and whole rock petrology and geochemistry to build a schematic...

Magma chamber processes over the past 475,000 years at Mount Hood, Oregon : insights from crystal zoning and crystal size distribution studies

Creator:: Darr, Cristina M.
Abstract:: Several different petrological techniques have been applied to lava flows between 200 to 475,000 years old from Mount Hood, Oregon. Mount Hood is unusual, in comparison to nearby Mount St. Helens and Mount Jefferson, in that it has produced relatively homogeneous lava compositions over 475,000 years. Erupted lavas are mostly...

An Investigation of Ceratomyxa shasta sporulation following death of itsChinook salmon host

Creator:: Soderlund, Krista M.
Abstract:: As pre-spawning mortality (PSM) in Chinook salmon in the Willamette River Valley becomes a more defined and examined area of study, more focus is granted to not only preserving the health of these fish, but also expanding knowledge concerning various pathogens that utilize the salmon as hosts and may be...
