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 ...
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 ...
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 ...
Evaluation of Catchment-Scale Stormwater Runoff Management on First-Flush Water Quality and Storm Discharge Quantity
(2018-12)
Urbanization and resulting imperviousness has caused increased pollutant loadings into receiving water bodies. One of the main sources of pollutant loads is stormwater runoff. The purpose of this study was to investigate ...
Making Satellite Sensors Better for Hydroclimatic Applications: Evaluation of NASA SMAP Soil Moisture Using Oklahoma’s Environmental Monitoring Network—MESONET
(2017-12-15)
Soil moisture, quantified as the ratio of liquid water to soil in volume or weight, is the measurement of the water that is held in the space between soil particles. Understanding the components of soil, particularly its ...
The Effect of Pore Water Evaporation on Transport of Caffeine, Propranolol, and Ciprofloxacin: A Sand Column Study and Model Simulation
(2016-12)
The purpose of this study was to explore the transport of selected pharmaceuticals under saturated and unsaturated conditions, simulating environmental processes of evaporation and flooding. Caffeine (a stimulant), ...
Assessment of Partial Joint Penetration Welds on Bolted End-plate Connections for use in Intermediate Moment Frames
(2016-05-13)
End-plate moment connections are a very common connection type used in the metal building industry today. Bolted end-plate connections are found where a rafter is joined to a column and consist of a steel plate welded to ...
