Consistency and effectiveness of advisory speeds: an evaluation of current posting techniques

Creator:: Rohani, Joshan W.
Abstract:: Crash rates are said to be nearly three times higher on curved sections than those on straight sections of rural roadways. As a result, advisory curve/speed signs are standard practice to mitigate these risks on sharp horizontal curves. The industry standard for determining appropriate and uniform speeds for such signs...

Framework for assessing the potential safety performance of construction mechanical and electrical field employees

Creator:: Moghaddam Vahed, Ali
Abstract:: In the field of construction safety, many researchers have worked to create assessment tools. These tools focus on different aspects of construction safety, such as assessing safety climate, safety culture, etc. Although research indicates that the majority of incidents are caused by unsafe behaviors and acts, there are no comprehensive...

Investigation of Drilled Shafts under Axial, Lateral, and Torsional Loading

Creator:: Li, Qiang
Abstract:: Drilled shaft foundations provide significant geotechnical resistance for support of structures, such as highway bridges, traffic sign, and signal pole structures, and are used widely to meet their structural foundation requirements. The amount of steel reinforcement in drilled shaft foundations has increased over the past several decades to account for...

Mooring analysis of the Ocean Sentinel through field observation and numerical simulation

Creator:: Baker, Joshua L.
Abstract:: This study presents a mooring analysis of the Ocean Sentinel buoy, which is a mobile test platform for Wave Energy Converters. The Ocean Sentinel is owned and operated by the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The study involved a field observation as well...

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....

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...

An Agent-Based Simulation for Emergency Warning Dissemination in a Multiplex Social Network

Creator:: Koll, Charles D.
Abstract:: The variety of natural disasters provide different sets of characteristics and properties with unique challenges. One significant difference between hazard types is prewarning lead time, the amount of time individuals have from a potential warning to the disaster occurring. Rapid onset disasters may not provide an official warning about a...

Morphodynamic Evolution of Coastal Oregon: Using New Lidar-derived Beach and Sand Dune Morphometrics to Explore Multi-decadal Change

Creator:: Light, Jacob W
Abstract:: The coast of Oregon is highly dynamic, with beach and dune morphodynamics constantly evolving in response to physical and ecological forcing at scales ranging from seconds to decades and meters to tens of kilometers. Evaluating spatial and temporal trends in shoreline evolution is paramount in understanding and eventually developing a...

Establishing a through-boring pattern and method of test for utility poles

Creator:: Elkins, Lori A.
Abstract:: The goal of this study was to optimize a through-boring pattern that will provide adequate preservative penetration while minimizing the reduction in overall pole bending strength. Hole spacing was developed using longitudinal and transverse chemical penetration data from previous studies. Finite element analysis was used as a preliminary assessment tool...

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...
