Application of GNSS for Vertical Reference Determination

Creator:: Kim, Su-Kyung
Abstract:: Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...

The Fundamental Behavior of Timber-Concrete Composite Floors in Fire

Creator:: Shephard, Annabel B.
Abstract:: Timber-concrete composite (TCC) floors have improved strength and stiffness when compared to timber-only floors, allowing for longer spans in buildings and improved life safety. However, North America does not have codes and standards that recognize TCC floors, particularly the improved life safety performance of these floors in fire. Therefore, alternate...

Sound and Vibration Analysis of Alternative Rumble Strips

Creator:: Horne, Dylan Ross
Abstract:: Roadway departure crashes accounted for 18,275 fatal crashes in 2017 across the United States (Jones et al. 2017). Rumble strips (RS) provide audible and haptic interior alert when a vehicle is departing the roadway reducing run-off-the road crashes. Although inexpensive to install, and easy to maintain, RS are not installed...

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

Numerical Investigations on Sewer Geysers

Creator:: Choi, YunJi
Abstract:: A sewer geyser is a series of ejecting air-water mixture eruptions through vertical shafts of drainage systems. In field observed geyser incidents, manhole covers were blown into the air and they were followed by ejecting air-water mixture eruptions that lasted for several seconds at a time. Trapped air in sewer...

Investigation of effectiveness of radar speed signs and additional lighting for speed control in highway construction and maintenance work zones

Creator:: Jafarnejad, Ali
Abstract:: Every year thousands of people are killed or injured in work zone crashes in the US due to excessive speed, distraction, inattentiveness, low visibility, and other factors. Roadway construction and maintenance operations often occur at night when the traffic volume is low, creating less congestion and delay to the traffic....
Resource Type:: Masters Thesis

Unsaturated Soils and Foundation Design : Theoretical Considerations for an Effective Stress Framework

Creator:: Baker, Josiah D.
Abstract:: This study presents the theoretical background necessary to model the bearing capacity of shallow and deep foundations in partially saturated soils. The conventional bearing capacity equations for shallow and deep foundations and the 𝛽-method for deep foundation side resistance have been modified to include the effects of matric suction and...
Resource Type:: Masters Thesis

Right-hook crash causality at signalized intersections

Creator:: Jannat, Mafruhatul
Abstract:: A Right-hook (RH) crash is a common type of bicycle-motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection. At signalized intersections, RH crashes can occur at the onset of the green or during the latter portion of the green phase. In spite of the...

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...
Resource Type:: Masters Thesis

Amplification of solitary waves along a vertical wall

Creator:: Li, Wenwen
Abstract:: Reflection of an obliquely incident solitary wave at a vertical wall is studied experimentally in the laboratory wave tank. Precision measurements of water-surface variations are achieved with the aid of laser-induced fluorescent (LIF) technique and detailed temporal and spatial features of the Mach reflection are captured. During the development stage...
