Application of Methods to Characterize VS30 in Alabama
(2022-08-03)
One of the most important characteristics of a soil that is a basis for seismic analysis, is shear wave velocity (VS). VS has proved to be a valuable tool for site response analysis for seismic design since it has the ...
Assessment of Bioenhanced Back Diffusion and Reductive Dehalogenase Gene Abundance in an Aquifer Cell Packed with Heterogenous Soils
(2023-04-26)
Remediation of chlorinated ethenes can be challenging at complex contaminated sites with low permeability soils acting as secondary source zones due to back diffusion of adsorbed contaminant mass. To better understand how ...
Assessment of Geochemical Reactivity in Geologic CO2 Utilization and Storage Systems
(2022-08-08)
Increasing atmospheric carbon dioxide concentration is a consequence of increasing energy consumption. As a result, developing ways to manage excess CO2 emissions has become a vital concern to avert the exacerbating effects ...
BEHAVIOR AND CAPACITY OF THERMALLY RESTRAINED MOMENT FRAME MEMBERS DURING COMPARTMENT FIRE
(2021-07-27)
In the event of a fire hazard, structural resistance depends on the ability to resist a comprehensive set of load combinations comprising the gravity loads and the thermally induced fire loads without undergoing failure. ...
Behavior of Steel Drop-In Connections Evaluated Utilizing Digital Image Correlation
(2024-12-09)
A safer and more efficient drop-in shear connection (compared to conventional shear tab
and double angle connections) has been proposed for implementation in the commercial and
residential steel frame building industry. ...
Biotransformation of Perfluorooctane Sulfonamide (FOSA), 8:2 Fluorotelomer Alcohol (8:2 FTOH), and 6:2 Fluorotelomer Sulfonate (6:2 FTS) in Aqueous Film-Forming Foam (AFFF)-Impacted Soils under Oxic and Anoxic Conditions
(2022-12-05)
The use of aqueous film-forming foams (AFFFs) for fire suppression over decades has resulted in contamination of numerous sites by per- and polyfluoroalkyl substances (PFAS). However, the environmental fate and transformation ...
Characterizing Strength Loss in High Plasticity Clays Along Alabama Highways
(2024-08-15)
Strength loss in high plasticity clay soils is a common occurrence along roadways in western and central Alabama and has considerable impact on pavement distress and slope failures. Approximately $16 million was spent to ...
Comparison of Vegetation Types for Prevention of Erosion and Shallow Slope Failure Along Roadways
(2022-08-03)
Shallow slope failures due to erosion are common occurrences along roadways in Alabama due to the prevalence of high intensity rainfall in the region. The use of vegetative covers is a reasonable solution to stabilize newly ...
Component Level Testing of a Large Area Maintenance Shelter
(2023-08-04)
Large Area Maintenance Shelters (LAMS) are used by the United States military as temporary shelters for equipment and maintenance. After several LAMS structurally failed in wind speeds within the design parameters, the Air ...
Composite Behavior of Steel-Precast and Steel-Mass Timber Shallow Floor Systems
(2024-07-26)
Girder-Slab Technologies composite shallow structural floor system is primarily used in mid-rise residential structures. The main component is the open-web dissymmetric steel beams (D-Beams), which are integrated between ...
A COMPREHENSIVE ASSESSMENT OF ALABAMA’S FUEL TAX ADJUSTMENT MECHANISMS AND ITS IMPACT ON TAXPAYERS’ FINANCIAL CAPACITY
(2024-12-06)
This thesis presents a comprehensive evaluation of fuel tax adjustment mechanisms intended to address Alabama's transportation demands without exceeding taxpayers' financial capacity. The study focuses on assessing the ...
A ‘Concentrate-&-Degrade’ Technique for Cost Effective Adsorption and Degradation of Per-and Polyfluoroalkyl Substances in Water
