Evaluation of Stereoscopic Camera Systems for Non-Intrusive Spatial Free Surface Measurement in Coastal Research Laboratories

Creator:: O'Day, Christopher S.
Abstract:: Physical modelling is instrumental to the progression of coastal engineering research and our understanding of the offshore and nearshore environments. Scaled models are designed and built to be tested in coastal research laboratories, where a wave basin or flume generates the desired wave conditions for experimentation. The surrounding hydrodynamics of...

A novel framework for uncertainty propagation in river systems based on performance graphs using two-dimensional hydrodynamic modeling

Creator:: Gifford-Miears, Christopher H.
Abstract:: This thesis presents a novel approach for propagation of uncertainty in river systems. Errors in data observations and predictions (e.g., stream inflows), in model parameters, and resulting from the discretization of continuous systems, all point to the need to accurately quantify the amount of uncertainty carried through the modeling process....

Design and environmental performance of near-surface mounted carbon fiber reinforced polymer strips for shear strengthening reinforced concrete bridge girders

Creator:: Goebel, Jacob Hans
Abstract:: During the interstate expansion of the 1950s, many conventionally reinforced concrete deck girder bridges were built throughout the country. These now vintage bridges commonly exhibit diagonal cracking and rate inadequately for shear, thus they are candidates for shear strengthening to extend their useful life. Near-surface mounted (NSM) retrofitting is a...

Behavior and analysis of pile caps with poor anchorage details

Creator:: Sorentino, Anthony William
Abstract:: Pile caps are structural elements used to transmit loads from structural columns into pile groups. A pile cap is generally constructed of reinforced concrete and contains only minimal flexural reinforcing steel. Using modern design methods, the anchorage of the flexural steel may limit the design capacity of existing pile caps....

Methods for strengthening flexural steel details in reinforced concrete bridge girders using a near-surface mounted retrofitting technique

Creator:: Amneus, Deanna
Abstract:: Many older reinforced concrete deck girder (RCDG) bridges contain straight bar terminations of flexural reinforcement. Common bridge design practice of the 1950s did not consider the additional demands on the terminated bars from shear and flexure. Moreover, more stringent code specifications and heavier permit trucks contribute to the insufficient ratings...

Flexural anchorage performance and strengthening on negative moment regions using near-surface mounted retrofitting in reinforced concrete bridge girders

Creator:: Barker, Laura
Abstract:: Large numbers of reinforced concrete deck girder (RCDG) bridges were built during the highway infrastructure boom of the 1950's. The advent of standardized deformed steel reinforcing bars during this time allowed for straight bar terminations in flexural tension regions. Designers of the time terminated reinforcing bars where they were no...

Mapping Nearshore Bathymetry with Spaceborne Data Fusion and State Space Modeling

Creator:: Forfinski-Sarkozi, Nicholas A.
Abstract:: Despite numerous techniques for measuring and estimating water depth, bathymetry in the nearshore zone is notoriously difficult to map. Dangerous sea states, noisy environmental conditions, and expensive survey operations, particularly in remote areas, contribute to the difficulties of obtaining data along the coast. Global datasets, derived mainly from satellite altimetry...

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)...

Dual Purpose Utilization of Titanium Alloy Bars for Impressed Current Cathodic Protection and Near Surface Mounted Retrofit in Reinforced Concrete Beams

Creator:: Slawinski, Amanda K.
Abstract:: Many older reinforced concrete bridges and buildings in the United States are considered deficient due to past design codes that are not conservative, increased loading, and deterioration of structural components. Deterioration is most commonly caused by corrosion, which reduces the steel cross sectional area and damages the concrete cross section....

Non-destructive determination of yield stress for in-situ gusset plates

Creator:: Pflaum, Therese Michelle
Abstract:: Failure of a gusset plate that caused the I-35W Bridge collapse in Minneapolis, MN resulted in mandated rating of connections by the Federal Highway Administration (FHWA). Rating connections requires material properties as an input. The material properties are generally reported on the available detailed drawings for bridges. However, some bridges...
