Static Load Testing of a Damaged, Continuous Prestressed Concrete Bridge

Fason, William (2009-05-15)

Shortly after the completion of interstate highway I-565 in Huntsville, Alabama, cracks were discovered in the continuous end of many of the prestressed concrete bulb-tee girders. Alabama Department of Transportation ...

Stochastic Fragment Velocity Analysis of Concrete Masonry Walls under Blast Loading with a Multi Degree of Freedom Model via the Monte Carlo Method

Hatfield, John (2024-04-29) ETD File Embargoed

The behavior of concrete masonry unit (CMU) walls under dynamic overpressure loading where dynamic fracture produces secondary fragments is quite complex. The response of a CMU wall is influenced by the material properties ...

Structural Performance of Self-Consolidating Concrete in AASHTO Type I Prestressed Girders

Boehm, Kurtis (2008-08-15)

As part of a larger investigation sponsored by the Alabama Department of Transportation (ALDOT) into the use of self-consolidating concrete (SCC) in bridge girders, this thesis documents a structural investigation of SCC ...

Theoretical Moment-Rotation Curve for Steel Piles Embedded in Concrete

Hammett, Stephen (2017-07-31)

The accurate modelling and analysis of connections formed by embedding steel piles in concrete is a difficult undertaking that has only recently begun to receive attention in the research community. These connections are ...

Time-Dependent Deformations in Precast, Prestressed Bridge Girders

Johnson, Brandon (2012-08-03)

Precast, prestressed girders are used across the state of Alabama for bridge construction. There has been a desire to allow self-consolidating concrete to be used to manufacture these bridge girders. The time-dependent ...

Transfer Length in Bulb-Tee Girders Constructed with Self-Consolidating Concrete

Dunham, Emily (2011-05-11)

This thesis is focused on the transfer bond behavior of self-consolidating concrete (SCC) relative to conventionally vibrated concrete (CVC) in full-scale, plant-cast, prestressed concrete bulb-tee girders for implementation ...

Update of Bridge Design Standards in Alabama for AASHTO LRFD Seismic Design Requirements

Law, Jordan (2013-04-19)

The Alabama Department of Transportation (ALDOT) has been required to update their bridge design specifications from the Standard Specifications for Highway Bridges to the LRFD Bridge Design Specifications. This transition ...

Use of Optimized Aggregate Gradations and Dust-of-Fracture Mineral Filler for Concrete Applications

Harrigan, Christopher (2015-12-04)

Many proportioning methods exist to help the designer achieve a well-graded, or optimized aggregate gradation in the concrete industry, but not all are effective. The Shilstone Method and percent retained chart have been ...

The Utilization of Alternative Fuels in the Production of Portland Cement

Swart, Dustin (2007-08-15)

The production of portland cement converts many different raw materials into clinker, in the presence of temperatures on the order of 1,500 degrees Celsius. Historically, nonrenewable fossil fuels have been used to maintain ...

WELDED WIRE SHEAR REINFORCEMENT FOR PRESTRESSED CONCRETE BRIDGE GIRDERS

Johnston, James (2022-11-28)

Welded wire reinforcement (WWR) is a steel product that is prefabricated into welded sheets. While this product is seeing use as shear reinforcement in precast concrete bridge girders for some states, other states, such ...
