Wind induced torsional fatigue behavior of truss bridge verticals

Creator:: Keller, Philipp
Abstract:: The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

Wheeled Mobility Devices Performance and Passive Securement Systems

Creator:: Mather, Andrea
Abstract:: Wheeled mobility devices (WhMD) pose unique safety risks to users while riding public transportation. Unsecured or improperly secured WhMDs create safety concerns for other transit riders and operators. Tests using accelerometers and visual observations were conducted to understand how WhMD orientation and securement in articulated buses, streetcars, and light rail...

Use of Virtual Visual Sensors in the Determination of Natural Frequencies of Timber Structures for Structural Health Monitoring

Creator:: Walker, Kristopher
Abstract:: Many nondestructive techniques for structural health monitoring are subjective and based on visual observations of degradation. In addition, dynamic properties of structures are already used to obtain quantitative structural health data. However, most current data collection is limited to localized damage on the structure, rather than global response. Recent research...

Tsunami loading on light-frame wood structures

Creator:: Linton, David B.
Abstract:: Since 2004 there have been multiple devastating tsunamis around the globe triggered by large magnitude earthquakes; with the most recent being the Tohoku, Japan tsunami in March 2011. These tsunamis have caused significant loss of life and damage to the coastal communities impacted by these powerful waves. The resulting devastation...

Transportation network connectivity, facilities encouraging walkability, and crime

Creator:: Bornasal, Floraliza B.
Abstract:: This thesis explores the relationship between crime, transportation network connectivity, and engineered facilities built to increase walkability through a case study of twenty-five sites within the city of Spokane, Washington. Using data spanning between 2008 and 2010, the author developed a GIS model representing conditions of the built environment, social...

Toward a mixture design methodology for internally cured concrete that considers filling specific pore sizes caused by self-desiccation

Creator:: Montanari, Luca
Abstract:: Internal curing is a term used to describe a process in which curing water is provided to a concrete mixture from inside the mixture. Internal curing water has typically been provided in North America mixtures by using prewetted porous materials, like fine lightweight aggregate (FLWA). Alternative materials, such as superabsorbent...

Tidal range changes in the Delaware Bay : past conditions and future scenarios

Creator:: Hall, George F.
Abstract:: Throughout the Holocene, appreciable changes in bathymetry are hypothesized to have resulted in large changes to tidal datums in coastal and estuarine areas. An understanding of tidal change is an important contribution to the knowledge of relative historical sea-level change and future coastal planning. To test this hypothesis, the Advanced...

The use of blended synthetic fibers to reduce cracking risk in high performance concrete (HPC)

Creator:: Bañuelos, José
Abstract:: High Performance Concrete (HPC) is used in our crucial pieces of infrastructure, such as bridge decks, due to its enhanced durability and engineering properties. However, HPC is highly susceptible to early-age cracking. Cracking within the first months of a bridge deck’s lifespan can severely hinder its long-term performance and durability....

The Location of the Neutral Axis in Wood Beams with Multiple Knots

Creator:: Voigt, Levi R.
Abstract:: In a homogenous and isotropic material, the location of the neutral axis coincides with the location of the centroid of the beam. Wood is anisotropic, meaning that it has different properties in different directions. It is also non-homogenous, meaning that the beam exhibits different properties at different locations throughout its...

The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...
