Advancing Spatial Data Engineering and Analysis: Integrative Approaches with GIS, Statistical Modelling, and Deep Learning

Creator:: Krivova, Maria
Abstract:: Geospatial data analysis is a multifaceted discipline encompassing the collection, processing, and visualization of diverse datasets. It models and delineates the interactions of people, objects, and phenomena within geographical spaces and predicts patterns based on the relationships between different locations. Despite significant advancements in geospatial data engineering and analytics over...

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...

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...

Strategies to Improve Density and Moisture Resistance of Asphalt Mixtures in Oregon

Creator:: Kumar, Vikas
Abstract:: Asphalt pavements constitute more than ninety percent of the nation’s roadway network. Besides serving the key role of providing a smooth and durable all-weather surface that benefits a range of users, they are also the lifelines of the nation and the world and contribute tremendously towards economic and social development....

Investigating Accelerated Carbonation Methods for Sequestering CO₂ into Lime Treated Soils

Creator:: Moore, Jaxom
Abstract:: Civil engineers frequently use lime to improve the mechanical properties of weak clayey soils. The production of lime is associated with significant CO₂ emissions. Sequestering carbon dioxide into the stabilized soil can effectively reduce the carbon footprint of the lime. In the presence of CO₂, unreacted lime in the stabilized...

Reactivity Testing of Waterglass and the Investigation into an Alternative Binder Enhanced with Cellulose Nanocrystals

Creator:: McAlexander, Melissa
Abstract:: Most of the concrete in the world is produced using hydraulic cement (ordinary portland cement, OPC) and siliceous or alumino-siliceous supplementary cementitious materials (SCM). Due to the shift in focus toward environmental sustainability within the construction industry, alkali-activated cementitious systems (AAC) have gained significant attention to reduce the carbon footprint...

Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

Creator:: Gestson, Sean Lyle
Abstract:: Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...

Experimental Testing of Glue-Laminated Beam-to-Column Connections

Creator:: Madland, Haley
Abstract:: The behavior of mass timber beam-to-column connections under seismic loading is not yet well understood. Mass timber beam-to-column connections must have the ability to maintain load-carrying capacity despite the deformations that will be imposed on all components of the building during seismic events. This behavior is called deformation compatibility. The...

Seismic Performance of Retrofitted Reinforced Concrete Columns Including Soil Structure Interaction

Creator:: Parson, Lance
Abstract:: There are many existing bridges around the world that were designed without consideration for seismic effects. Many of these bridges were designed before modern earthquake engineering design standards and practices existed and thus are expected to perform poorly during strong ground shaking. Common structural deficiencies are found in their reinforced...

Applying climate change information to hydraulic and hydrologic transportation infrastructure

Creator:: Al Naabi, Rawan Y.
Abstract:: Scour is the main cause of bridge failures in the United States. Bridge failures raise a hazard to the safety of the traveling public as well as the massive economic consequences due to the high cost of constructing a new or a replacement bridge. The Oregon Department of Transportation (ODOT)...
