Seasonal variations in tidal dynamics, water quality and sediments in the Alsea Estuary

Creator:: McKenzie, David Roller
Abstract:: During 1973 data was collected to analyze the seasonal variations of the tidal dynamics, water quality and sediments of the Alsea Estuary. A summary of historical information with a list of all known alterations to the estuary was made. A complete physical description, including the geographical setting and mixing classification...

A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

Creator:: Hyatt, Charles
Abstract:: In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

Pedestrian distraction : pedestrian behaviors at midblock crossings considering geometric and environmental conditions

Creator:: Kautz, Julia Anne
Abstract:: Pedestrian distraction at roadway crossings has been correlated with a higher risk of pedestrian-vehicle collisions due to the pedestrian's cognitive, visual, and motor attention being drawn to a wide variety of secondary tasks. This study is different from previous field studies of pedestrian midblock crossings in that the geometric layout...

Transportation Infrastructure to Support Bicycling in Dense Urban Environments : Design and Operational Considerations for Bicycle Lanes in Proximity to Commercial Vehicle Loading Zones

Creator:: Ghodrat Abadi, Masoud
Abstract:: While sophisticated plans have been adopted nationally and globally to increase bicycling’s share of daily commutes, safety concerns have negatively impacted targeted bicycling growth. Specifically, truck traffic plays a pivotal role in bicyclists’ perceptions of safety and comfort, because of the severe consequences of bicycle-truck collisions. Several types of engineering...

Development of structural layer coefficients for open graded asphalt emulsion mixes

Creator:: Hatch, David Russell
Abstract:: This paper describes the development of structural layer coefficients for open graded asphalt emulsion surfacing layers which can be used with the AASHO pavement design method, as modified by the U. S. Forest Service, Region 6. A field survey conducted to document the history, performance and material characteristics of in-service...

Depth estimation and frontal imaging via X-band marine radar

Creator:: Honegger, David Andrew
Abstract:: This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...

The effect of hold-down misplacement on the strength and stiffness of wood shear walls

Creator:: Lebeda, Dana J.
Abstract:: The objective of this study was to determine the effect of misplaced hold-downs on the static and cyclic behavior of wood shear walls. Three shear wall configurations were considered in this study. The first configuration (control) had hold-downs at the ends of the wall (wall type 1), the second configuration...

Performance of High-Strength Steel Reinforcement in Shear Friction Applications

Creator:: Matus Casanova, Nicolas A.
Abstract:: The use of high strength steel reinforcement has the potential to provide economic and constructability benefits when used in reinforced concrete structures. However, more research is needed to justify and confidently allow its use. Current design provisions limit the nominal yield strength of reinforcing steel bars to 60 ksi (420...

High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

Creator:: Nielson, Drew R.
Abstract:: Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...

Numerical Analysis of a Spine as a Retrofit of a Moment-Resisting Frame

Creator:: Rivera Torres, David M.
Abstract:: Steel moment-resisting frames (MRFs) are widely used in the United States to resist seismic forces. MRFs have many advantages, including architectural versatility, vetted member and connection detailing requirements, and high ductility for special MRFs (SMRF). However, MRFs require large members to meet story drift criteria. Moreover, strong-column-weak-beam requirements can result...
