Evaluation of Surface Preparation and Bond Angle Combinations for Joint Replacement using Ultra-High Performance Concrete
(2018-05-12)
Deterioration of bridges is often attributed to declining performance of the longitudinal connections between precast members or transverse deck joints. Ultra-high performance concrete (UHPC) is a cementitious composite ...
INFLUENCE OF RETARDERS ON SHRINKAGE AND COMPRESSIVE STRENGTH IN RAPID SET CONCRETE
(2018-05-12)
The purpose of this project is to study the influence and behavior of citric acid on calcium sulfoaluminate (CSA) concrete and compare with industry standard retarders. A review of the available literature on calcium ...
Feasibility of Blast Furnace Slag for Stabilizing Sulfate-Bearing Soil
(2023-12-15)
Calcium-based stabilizers are frequently used by The Oklahoma Department of
Transportation (ODOT) to enhance the strength and reduce the swelling potential of fine-grained
soils. However, these stabilizers can lead to ...
Comparative Hydraulic and Cost Analyses of Single and Dual Water Distribution Systems Using Nonpotable Water for Urban Irrigation in Norman, Oklahoma
(2017-12)
Drought has caused water resource shortages throughout Western and Midwestern United States for many years, particularly in California, Nevada, Arizona, Texas, and Oklahoma. This has led many communities to evaluate alternate ...
TOTAL WATER LEVEL MODELING IN THE NORTH CAROLINA COASTAL PLAIN: COMPARING ADCIRC AND HEC-RAS
(2017-12-15)
The purpose of this Master’s thesis was to develop and compare an ADCIRC and ADCIRC/HEC-RAS paired model for the purpose of total water level forecasting using the Tar River and Pamlico Sound area as a test case. ADCIRC ...
Modeling and Designing a Vertical Isolation System Using a Laterally Loaded Arch as a Negative Stiffness Element
(2022-05)
Structures, artwork, and expensive equipment are often susceptible to significant damage from vertical dynamic motion such as that generated by earthquakes. Several systems exist which seek to mitigate damage caused from ...
Feasibility Study of Geosynthetic Reinforced Soil Integrated Bridge Systems (GRS-IBS) in Oklahoma
(2016-05)
Bridges supported on deep foundations constitute the conventional and standard construction practice. While deep foundations provide several advantages for bridges with respect to their stability and performance, they also ...
Implementing Fiber-Reinforced, Self-Consolidating Concrete as a Repair Material for AASHTO Prestressed Concrete Girders
(2018-08)
In 2017, the American Society of Civil Engineers released a report card stating that, of the 614,387 bridges in the United States, nearly 40% are past their design life. Within a few months of the report, the U.S. Department ...
UNDERSTANDING THE SEISMIC RESPONSE OF SINGLE HELICAL PILES IN DRY SANDS USING A LARGE-SCALE SHAKE TABLE TEST
(2017-05)
Helical piles are deep foundations composed by a steel shaft and single or multiple helical plates welded at their tip or throughout their lead section, respectively, which allows them to be screwed into the ground during ...
Monitoring Norman, Oklahoma for temporal variation in SARS-CoV-2 using wastewater during University of Oklahoma football games
(2022-05)
Coronavirus Disease 2019, more commonly referred to as COVID-19, is the disease caused by the virus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). It is difficult to then get an accurate measure of cases ...
