Evaluation of Shear Tab Connections as Supplemental Energy Dissipators
(2022-11-04)
As structural engineering practice moves from life-safety to functional recovery after a significant seismic event, taking advantage of structural components to enhance the energy dissipation of a structure will be important. ...
Evaluation of Subsurface Gypsum-rich Rock in the Context of Geologic Carbon Sequestration
(2023-11-29)
Geological carbon sequestration is a promising means of reducing atmospheric carbon dioxide emissions by capturing CO2 gas and storing it long term in subsurface porous rock. The goal of geologic carbon sequestration is ...
Experimental Investigations on pressure pulses through different porous media
(2023-08-16)
Fluid mechanics traditionally and significantly investigate transient flows, which find applications ranging from flows in pipelines to porous media flows linked to water extraction and hydrocarbons. However, the nature ...
Experimental Testing and Analysis of S50 Beam with Finite Element Modeling of Splice Connection
(2021-12-08)
Large Area Maintenance Shelters, LAMS, are commonly used as deployable shelters by the US Air Force to store and maintain equipment. This work is specific to the LAMS located at Tyndall Air Force Base manufactured by ...
Exploring Targeted Long-Distance Travel Survey Sampling Frame Approaches to Support Travel Survey Collection
(2022-08-05)
Long-distance travel continues to grow in economic, environmental, and infrastructural importance. To inform policy, infrastructural funding, and travel demand forecasting, detailed travel survey findings are needed at the ...
Feasibility Studies on the Design and Usage of Steel Pile Piles for ALDOT Bridges
(2023-08-09)
Large diameter steel pipe piles provide an efficient and cost-effective alternative to conventional reinforced concrete bridge piles (drilled shafts) and steel piles (HP-piles). The steel pipe columns offer increased ...
Finite Element Modelling of Large Area Maintenance Shelters and Comparison to Experimental Results
(2021-08-16)
Large area maintenance shelters (LAMS) are used as temporary structures by the United States Air Force to provide shelter for helicopters, tanks, wheeled vehicles, and aircraft. There are several different brands of LAMS ...
Forensic Analysis of a Large Volume Rack Building Impacted by Hurricane Michael (2018)
(2021-12-02)
Metal building systems (MBS) are extremely common and frequently used in commercial, industrial, and warehouse applications thus serving critical roles in local economies. Damage sustained to these buildings through extreme ...
FULL-SCALE MECHANISTIC AND PERFORMANCE INVESTIGATION OF A FLEXIBLE PAVEMENT WITH A STABILIZED FOUNDATION
(2021-06-21)
The current study aimed to develop a mechanistic understanding of the behavior of flexible pavements with stabilized foundations through full-scale testing, instrumentation, and simulation. In pursuit of this objective, a ...
Hydrodynamic and Water Quality Modeling of Lake and Estuary Systems Considering Inflow and Outflow Effects
(2023-12-06)
Algal bloom, fish kill, hypoxia, and toxicity are some of the water quality issues faced by many waterbodies, from lakes to estuaries. Internal or external nutrients cause excess growth of algae and then lead to low or no ...
Hydrodynamics Modeling to Study the Impacts of Hurricanes without and with NNBFs in the Coastal Region of Mobile Bay
(2023-12-07)
The coastal communities of Mobile Bay, AL, are facing a serious problem of flooding due to storm surges. With the increasing economic and social activities along with the increasing frequency as well as the intensity of ...
Identifying Effectiveness of Engineering Traffic Control Devices for Wrong-Way Driving from the Driver Behaviors Perspective
(2023-01-09)
This dissertation aims to identify the effectiveness of engineering traffic control devices for wrong-way driving (WWD) from a driver behavior perspective, which contains two tasks: i) WWD fatal crash analysis, and ii) ...
Immediate Deflections of Simply Supported, Bonded, Class T and Class C Prestressed Concrete Beams
(2023-04-17)
Design practice for prestressed members has moved toward allowing partially prestressed members, which are allowed to crack under service loads. To define design requirements, the ACI 318 Building Code explicitly defines ...
Impact of overloaded vehicles on bridges
(2021-08-03)
Excessive weight and a growing number of overloaded vehicles can cause an accelerated consumption of bridge service life. Therefore, there is a need to control the operation of heavy traffic. This study considered the ...
Improvements in Construction Stormwater Treatment using Flocculants
