Evaluation of Setback Crosswalk to Mitigate Vehicle-Pedestrian Conflicts at Intersections

Creator:: Chai, Eileen Pei Ying
Abstract:: It is considered best practice when designing pedestrian access at intersections to provide two curb ramps at each street corner. In Oregon, there are many locations where long ramp runs cause curb ramps to be set back a significant distance from the apex of the intersection corner to meet this...

Synergistic Effects of Alkali Silica Reaction (ASR) and Fly Ash on the Corrosion Characteristics of Reinforced Concrete Systems

Creator:: Mazarei, Vandad
Abstract:: Alkali silica reaction (ASR) and corrosion of reinforcement are two deterioration mechanisms in reinforced concrete (RC) structures. These deterioration mechanisms can significantly damage a RC structure and reduce its service life. Supplementary cementitious materials (SCMs) are commonly used to improve the durability of RC systems containing reactive aggregate that are...

Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

Creator:: Smith, Jeremy A.
Abstract:: High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

Applying the Mixed Logit Model with Heterogeneity in Means and Variances to Pedestrian Injury Severity Outcomes

Creator:: Umphress, James
Abstract:: Walking is the single most universal mode of transportation in the world, but being a pedestrian exposes a traveler to high risk. Historically, pedestrians have consistently experienced disproportionately high rates of fatalities and severe injuries in traffic crashes. Research has probed into factors influencing pedestrian crash injury severity outcomes, but...

Identifying and prioritizing research gaps for the incorporation of fires in life cycle analysis of structures: A Delphi survey of international experts

Creator:: Thorp, Tiana Noelani
Abstract:: Civil engineers are aware of the impacts of structures on the global environment but the environmental impacts of a fire within these structures remains unknown. Fires present a unique hazard as it is difficult to predict the probability of the occurrence and the intensity. Traditional methods to identify the environmental...

Hydrodynamic Modeling of Submerged Wave Energy Converters: Power Take-Off Mooring Configuration Effect on Power Performance

Creator:: Meek, Moira H.
Abstract:: Wave energy converters (WECs) show promising potential to significantly contribute to global renewable energy goals. Numerous WEC designs have been proposed and investigated, but wave energy conversion technology has yet to reach convergence in the same way wind or solar has. Of the designs currently in existence, surface-piercing WECs are...

From Perception to Planning : Adaptation in Flood-risk Communities

Creator:: Gomez, Luis A.
Abstract:: This research asserts that flood risk perception of individuals living in floodplains influences their preparedness for taking actions to protect themselves from flood hazards. The results of this research are backed up by quantitative analysis of survey responses of individuals living in floodplains of Corvallis, OR in the USA. The...

Effects of Moisture Intrusion on the Performance of a Cross-Laminated Timber (CLT) Angle Bracket Connection

Creator:: Bora, Shrenik S.
Abstract:: Cross-laminated timber (CLT) is revolutionizing the use of wood in the construction sector of North America as a solution for walls and diaphragms in mid-rise or even high-rise timber structures on account of its environmental advantages, high strength-to-weight ratio, fire-safety performance, and propensity for prefabrication. However, considering the hygroscopic nature...

Wave Resource Assessments: Spacio-Temporal Effect of Wave Energy Converter Scale and Blue Economy Opportunities

Creator:: Dunkle, Gabrielle R.
Abstract:: Wave energy has the potential to power large and small factions of economies around the world alike. Current methods for determining the amount of wave energy resource available to wave energy converter (WEC) devices entail capturing the look of the sea state at large by presenting characteristic wave heights, periods,...

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...
