Life-Cycle and Playability Analysis of Natural Turfgrass and Synthetic Infill Playing Surfaces Under Field Conditions

Creator:: Daviscourt Brian L.
Abstract:: The perception of a long-term cost advantage of synthetic infill turf systems relative to natural grass systems has contributed to a rise in their popularity in the USA. However, few comprehensive cost assessments of natural grass and synthetic infill systems exist. There are also no studies looking at interactions between...

Application of Titanium Alloy Bars for Strengthening Reinforced Concrete Bridge Girders in Flexure

Creator:: Vavra, Eric
Abstract:: Structurally efficient and cost-effective solutions are needed to extend the service-life of deficient and aging highway infrastructure around the world. One critical need is to increase the flexural strength of older reinforced concrete (RC) structures to carry heavier and more frequent loads. Titanium alloy bars (TiAB) offer a new opportunity...

Seismic Performance of Square Reinforced Concrete Columns Retrofitted with Titanium Alloy Bars

Creator:: Lostra, Mackenzie M. W.
Abstract:: Large numbers of reinforced concrete (RC) bridges were built in the past that are now considered seismically deficient. The structural members most likely to be considered deficient are the supporting columns. Typical deficient columns contain inadequate transverse reinforcement and poorly detailed lap splice lengths above the foundation. Insufficient lap splice...

Shear strengthening reinforced concrete bridge girders using near-surface mounted titanium alloy bars

Creator:: Knudtsen, Jonathan
Abstract:: Aging and deficient infrastructure has become a major problem throughout the world. This is particularly evident in the case of reinforced concrete (RC) bridges. The cost of replacing these bridges is often prohibitive, thus engineers must find ways to strengthen them. Many older RC bridges predate the modern understanding of...

Bridge Damage State Detection Based on Strain-Based Wireless Structural Health Monitoring

Creator:: Slaven, Kelli R.
Abstract:: The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...

Rivers and Roads : Exploring How Environmental Governance Impacts State Management of Forest Roads

Creator:: Detwiler, Stacey M.
Abstract:: This study explores how environmental governance mechanisms affect state management of forest roads to address the chronic delivery of sediment to streams in Oregon, Washington, and California on private and state forestlands. Forest roads can degrade water quality and harm aquatic life when runoff mobilizes fine sediments from the road...

A Microgrid Design Case Study : Synchrophasor Placement and Development of a Protection Laboratory for the Oregon State University - Corvallis Campus

Creator:: Huo, Chen
Abstract:: In the past two years, Oregon State University (OSU) Corvallis campus suffered several power outages. The estimated cost of one of those outages was close to a million dollars worth of equipment and impact on research projects. Meanwhile, the campus grid operates with severely aging power assets. The reliability of...

Economic Analysis of A Road Usage Charge

Creator:: Ke, Yue
Abstract:: This study evaluates the distributional impacts of an alternative public roads finance method, a road usage charge (RUC) fee, on lower income households and rural households in Oregon. While previous research has relied on the 2001 and 2009 National Household Travel Survey (NHTS), this research will uses the 2011-2013 Oregon...

Where the Stream Meets the Road : Prioritizing Culvert Replacement for Fish Passage

Creator:: Reagan, Rachel E.
Abstract:: Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific...

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...
