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 ...
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 ...
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 ...
Method of Rehabilitation for Corrosion Damage in The End Region of Prestressed Concrete Bridge Girders
(2021-12-17)
Two of important factors in longevity of prestressed concrete bridge girder are the effect of corrosion to prestressing reinforcement in concrete and process of stress transferring from prestressing strands to concrete. ...
Impact of Soil pH on the Leaching Rate of Disposed Li-ion Batteries
(2021-05-14)
Lithium-ion batteries (LIB) are becoming the front-runner for rechargeable battery usage yet are rarely disposed of properly. Analysis of varying landfills and electronic waste recycling centers throughout the world show ...
Evaluation of long-term performance of in-stream channel stability structures for protecting Oklahoma bridges and roads
(2021-08)
Streambank erosion can damage bridges, hydraulic structures, and private property. In-stream structures may be installed to control river migration and limit bank erosion during large precipitation events. Historically, ...
End Regions Repair of Prestressed Girders for Restoring the Shear Capacity Using UHPC, FR-SCC, and MALP
(2021)
One of the most important concepts in prestressed concrete is stress transfer from prestressing strands to the surrounding concrete. The efficiency of this process dictates the overall quality of the structural member, ...
Remote Sensing of Hydrologic Variables in Rivers
(2020)
The use of a “rating curve”, an empirical relationship between water depth in a river and the volumetric flux of water, or discharge, is subjected to uncertainty in data extrapolation, complexity due to changes in channel ...
Application of basalt fiber reinforced polymer rebar for prestressed concrete beams
(2022-08)
All steel reinforced concrete infrastructure that is facing a chemical environment and
corrosion will have their service life greatly reduced. With time it will lead to a premature and an
inevitable failure of the steel ...
Biological sulfate removal using waste organic substrates in continuous flow-through columns simulating mine water vertical flow bioreactors
(2020)
In mine water passive treatment systems, biological sulfate (SO42-) reduction in vertical flow bioreactors (VFBRs) is often utilized to precipitate trace metals as metal sulfides and to generate alkalinity. Sulfate removal ...
