3-D Model Development of Metal Building Systems with Hard Walls
(2016-04-05)
Metal Buildings with precast concrete or masonry walls (hard walls) have been identified by analytical modeling, shake table tests, and earthquake reconnaissance as being susceptible to collapse. While the steel frames ...
Acoustic Emission Testing of Repaired Prestressed Concrete Bridge Girders
(2011-05-04)
Acoustic emission (AE) monitoring has proven to be a useful nondestructive testing tool in ordinary reinforced concrete beams. Over the past decade, however, the technique has been used to test other concrete structures ...
Advanced Computing Techniques in Structural Evaluation of Flexible Pavements Using the Falling Weight Deflectometer
(2012-07-25)
The use of nondestructive deflection testing has become an integral part of the structural evaluation and rehabilitation process of pavements in recent years. The falling weight deflectometer (FWD) is commonly used to ...
Advanced physical and chemical characterization of oil spill residues
(2019-04-18)
Oil spill contamination is a worldwide problem. On April 20th, 2010, the Deepwater Horizon (DWH) oil platform located off the coast of Louisiana exploded and sank after 2 days. The wellhead could not be sealed until July ...
Air Entrainment and Acoustic Wave Celerities Following a Rapidly Moving Pipe Filling Bore
(2015-04-30)
Water mains stormwater sewers and tunnels may undergo processes of rapid filling, in which
flow regimes transit from open channel into pressurized flows. In the process, air bubbles may
be entrained, which may influence ...
Air Pocket Modeling in Water Mains With an Air Valve
(2012-01-27)
Water mains filling events follow certain maintenance operations that require the complete or partial emptying of pipelines. These operational procedures are performed carefully in order to prevent air pocket formation, ...
Air-Water Interface Flows in Pipe Emptying
(2020-07-15)
Pipe emptying is an important component of water supply operations. Pipes can be drained as a scheduled operation preceding maintenance, flushed for health reasons or they may empty as a result of an accidental break causing ...
Alternative Fuels and Their Effects on Portland Cement
(2010-07-19)
The production of portland cement is a complex process involving several materials, complex systems, and temperatures on the order of 1500 °C. Non-renewable fossil fuels such as coal, petroleum coke, and natural gas have ...
Alternative Solid Fuels for the Production of Portland Cement
(2008-12-15)
Portland cement manufacturing involves the combustion of fuels with various raw materials at approximately 2,700 °F (1,500 °C) to produce clinker. Fuel costs and environmental concerns have encouraged the cement industry ...
Analysis of Distress Along U.S. 331, Montgomery, AL Between Mile Markers 88.480 and 91.070
(2013-04-29)
This report investigates the cause of asphalt concrete pavement distress along U.S. 331 between mile markers 88.480 and 91.070. The distress consisted of standalone bumpy sections of the asphalt concrete pavement, all less ...
Analysis of Freeway Traffic Operations using Driver Assistive Truck Platooning Technology
(2016-07-26)
Driver assistive truck platooning (DATP) as an application of cooperative adaptive cruise control is expected to have substantial benefits in the freight industry. This FHWA study looks into the benefits of DATP in the ...
Analysis of Manufactured Home Vulnerability in Extreme Winds
(2020-07-16)
Fatality rates are higher in mobile and manufactured homes (MMH) than in permanent site-built homes during tornadoes. The physical processes driving the enhanced fatality rates have not been fully explored, but must be ...
Analysis of Slope Failures Along Alabama Highways
(2018-08-20)
Slope stability management systems (SSMSs) have been developed by multiple state transportation agencies to assess landslides adjacent to highways—aiding in the effective allocation of resources for slope and/or roadway ...
An Analysis of the Municipal Solid Waste Permitting and Recycling Programs of the State of Alabama
(2013-11-08)
In the past half century solid waste policy has changed significantly as public awareness and the realization of potential environmental hazards of landfills has grown. The State of Alabama has recently begun to experience ...
An Analytical Investigation of Transverse Joints in Precast-Panel Bridge-Deck Replacement Systems
(2012-08-15)
In recent years precast bridge deck panels have offered a solution for rapid bridge deck rehabilitation by minimizing traffic interruption and accelerating construction. Cracking and early deterioration of the connections ...
Analytical Solutions for Sequentially Coupled Multi-Species Reactive Transport Problems
(2007-12-15)
Multi-species reactive transport equations coupled through sorption and sequential first-order reactions are commonly used to model sites contaminated with radioactive wastes, chlorinated solvents and nitrogenous species. ...
Application and Evaluation of WEPP in a Forested Watershed with Perennial Streams
(2010-01-06)
Forests generally have low erosion rates unless they are disturbed by harvesting operations or road construction. These common disturbances typically cause increase in the sediment yield which is reduced after vegetation ...
The Application of Self-Consolidating Concrete (SCC) in Full Scale Drilled Shafts
(2010-08-09)
Drilled shafts are being built larger and deeper, and this has increased the challenge in creating quality drilled shafts. Due to longer placement times and more required reinforcement, problems have been discovered with ...
