Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

Creator:: Johnson, Brandon Ang
Abstract:: Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...

Pressure distribution around a circular cylinder resting on a flat boundary in an oscillating fluid

Creator:: Johnson, Ronald Ernest
Abstract:: This study was undertaken to provide information needed in the design of ocean outfalls. A review of past investigations concerning forces on submerged objects is presented. Objects independent of any boundary and cylinders in boundary contact are considered. A solution for pressure distribution about a circular cylinder resting on a...

Performance-Based Design Methodology for Using Emergent Vegetation to Mitigate Wave Overtopping

Creator:: Ostrow, Kayla
Abstract:: To facilitate the design of Natural and Nature-Based Features (NNBF) for flood protection, this thesis expands an existing engineering design methodology to NNBF systems. The existing approach is a Level III reliability method for the performance-based design of traditional coastal engineering systems. The expanded methodology incorporates uncertainties inherent to both...

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

Creator:: Utt, Michael Ernest
Abstract:: Seasonal data on tides, water quality and sediments in the Siuslaw Estuary were collected. Tide and velocity data were analyzed to evaluate damping conditions in the estuary. The system was found to approximate a weakly damped standing wave. A strong relationship of damping conditions to river flow was observed. The...

Evaluation of Cycling Behavior: Factors that Influence Bicyclists’ Comprehension, Comfort, and Stress

Creator:: Cobb, Douglas P.
Abstract:: Travel demand has increased due to population growth, increase of vehicle ownership, and development patterns resulting in greater levels of congestion, pollution, and crash frequency. One approach to demand management is to increase the share of trips made by bicycles. With the increase in bicycling rates, there is a critical...

Impact of Bicycle Rolling Stop Laws on Safety-Relevant Behaviors in the Pacific Northwest

Creator:: Woodside, Jasmin Barnes
Abstract:: Previous research has found some bicyclists disregard circular red indications and stop signs. Possible justifications include a desire to increase safety, save energy, save time, and increase visibility. Because of this, many bicyclists feel as though stopping at stop signs, especially in the absence of conflicting vehicular traffic, is an...

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...

Experiments on cable strumming and flow induced drag

Creator:: Barnes, Bert Lee
Abstract:: Short non-flexible elements of cable were driven harmonically in water while constrained by springs. The cable elements were observed to oscillate at approximately the Strouhal vortex shedding frequency. Damped resonance occurred near the point where the natural frequency and the Strouhal vertex shedding frequency were equal. Transverse oscillation amplitudes greater...

Modeling solute transport by centrifugation

Creator:: Celorie, Jay A.
Abstract:: Measurement of physical and chemical solute transport properties of a soil/waste system is necessary to predict pollutant migration in soils. The adsorption component of solute transport is most often determined in the laboratory by performing column studies and batch equilibrium tests. Both of these methods suffer from disadvantages. Batch equilibrium...
