Development, Numerical Implementation, and Application of Methods to Simulate Solute Transport Processes in Porous Media Systems
(2019-04-16)
Solute transport in porous media has been the attention of a plethora of studies over the last several decades. This research identifies gaps in existing knowledge within the realm of solute transport in porous media systems ...
Development, Testing, and Analysis of a Rotational Friction Connection for Improving the Seismic Performance of Metal Building Systems with Hard Walls
(2018-07-27)
The use of metal building systems has become commonplace in today’s society. For well over two decades, the performance of metal building systems during seismic events has been the subject of intense research. It was ...
Dewatering Rock Crushing Fines Using Geotextile Tubes
(2010-01-06)
A study on dewatering rock crushing fines using geotextile tubes was conducted. The laboratory portion included rapid dewatering tests and hanging bag tests to evaluate the dewatering efficiencies of the geotextiles as ...
Documentation of the Rapid Replacement of Four GDOT Bridge Decks
(2006-05-15)
The Alabama Department of Transportation (ALDOT) has many interstate bridges near downtown Birmingham which have good substructures and superstructures, but suffer from significant deck cracking and deterioration. The ...
Drained Residual Strength of Expansive Soils Causing Pavement Distress along Alabama Highway 5
(2019-11-15)
A segment of Alabama Highway 5 (AL-5) located in Perry County, Alabama has been experiencing severe pavement distress that is mostly caused by the behavior of soil beneath the roadway. AL-5 is a farm-to-market road that ...
Durability of Nitinol for Structural Applications
(2006-08-15)
Nitinol is a shape memory alloy that has recently been studied for its suitability as a material in energy dissipation devices in structures. The alloy has excellent structural capabilities in terms of strength and ...
Dynamics of Saltwater Intrusion Processes in Saturated Porous Media Systems
(2012-08-14)
The overarching goal of this dissertation is to contribute towards a better understanding of the dynamics of saltwater intrusion and the associated transport processes in coastal groundwater systems. As a part of this ...
Early Characterization and Performance of a Flexible Thick Lift Pavement
(2019-12-05)
The South Carolina Department of Transportation (SCDOT) has recently been experimenting with thick lift paving to increase construction speed and facilitate faster access to traffic. However, there has been limited research ...
Early-Age Behavior of Lightweight Aggregate Concrete
(2011-11-28)
Early-age cracking can be a severe problem in concrete as it can reduce the service life of the structure. In this project the early-age behavior of concrete was measured, evaluated, and modeled. The early-age stress ...
Early-age cracking of mass concrete structures
(2007-05-15)
Early-age cracking is a recurring problem in many mass concrete structures. Currently agencies tend only to limit the maximum temperature difference that may develop in a mass concrete structure in an attempt to mitigate ...
Earthquake Induced Inelastic Demands on Buckling Restrained Braces
(2015-07-29)
Buckling restrained braces (BRBs) show an increasing popularity in modern designs due to their high ductility capacity over conventional braces. Non-linear tests on isolated BRBs have shown the symmetrical hysteresis ...
An Ecologically-Sustainable Surface Water Withdrawal Framework For Cropland Irrigation-A case study in Alabama
(2009-04-22)
Agricultural production in the State of Alabama, USA, mostly depends on natural rainfall. Because of this and also because of low and uncertain precipitation levels during growing seasons, agricultural production in Alabama ...
Effect of Core Geometry and Size on Concrete Compressive Strength
(2014-11-06)
To evaluate the in-place concrete strength for acceptance for a structural member with potentially substandard strength, the compressive strength of cores may be required for assessment. Depending on the geometry and size ...
