3-D Model Development of Metal Building Systems with Hard Walls

Langley, Michael (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 ...

Analysis and Optimization of Multilayered Airfield Pavement Resilience

Whitmore, David (2021-04-02) ETD File Embargoed

The overall objective of this research was to optimize the individual layers of a multilayered airfield pavement to make the pavement more resilient to blast and impact loadings when compared to a baseline rigid pavement. ...

Characterization of Multi-Phase Performance-Based Passive Control Systems

Rawlinson, Taylor (2011-10-27)

Typical passive control devices have inherent strengths and weaknesses as seismic protection systems. A Multi-phase Passive Control System (MPCS) combines two types of passive control devices in a system in order to offset ...

Characterization of the Behavior of High Volume Fly Ash Concrete

Keith, Kevin (2011-08-11)

Fly ash is commonly used as a supplementary cementitious material (SCM) in the production of portland cement concrete. Concrete produced with high fly ash replacement levels is considered high volume fly ash (HVFA) concrete. ...

Creep and Shrinkage Behavior of Concrete in Segmental Bridge Applications

Cooper, Grant (2020-11-23)

The objective of this study is to accurately predict creep and shrinkage behavior of concrete in the I-59/I-20 segmental bridge located in downtown Birmingham, Alabama. In order to quantify creep and shrinkage, four different ...

Design and Calibration of Stress Sensors on 4H-SiC

Chen, Jun (2022-03-07)

Stresses in electronic packages due to thermal and mechanical loadings can cause premature mechanical failures such as fracture of die, severing of connections, die bond failure, solder fatigue, and encapsulant cracking. ...

Development and Application of Composite Beam Theory on FRP Reinforced Concrete Flexural Members

Sha, Xin (2021-01-19)

Although there are specifications and approaches for the design of concrete flexural members reinforced with FRP, most of them were derived from empirical data. In order to obtain the rigorous theoretical definition of ...

The Development of a Decision Algorithm to Aid in the Selection of Pipe Material for Cross-Drainage Application

Tocci, Megan (2016-05-05)

The Code of Federal Regulations effectively limited allowable culvert materials to reinforced concrete pipe and corrugated steel pipe on Federal-aided projects. Angered by the exclusion, the plastics industry lobbied ...

Development of a Mass Concrete Specification for Use in ALDOT Bridge Construction

Gross, Eric (2017-08-29)

Special precautions must be taken when constructing concrete elements designated as mass concrete. These precautions may be satisfied through the formation of a mass concrete specification. Temperature requirements must ...

Development of a Single-Degree-of-Freedom Algorithm for the Analysis of Buried Composite Pipes Subjected to Internal Dynamic Pressure

Sadler, Dustin (2011-12-05)

The overall objective of this research project was to develop a practical engineering methodology for the analysis of underground composite pipes subjected to internal dynamic loading. The need for this analytical methodology ...

Development of composite beam theory and its application in composite and prestressed concrete structures

Bai, Fengtao (2016-05-13)

For some complex structural engineering problems like behavior of sandwich structures and prestressed concrete structures, extensive experimental works and finite element analyses might not be able to help understand the ...

Development of Criteria for Fatigue Design of Horizontally Curved Steel Bridges

Jalali Moghadam, Sayed Mohamad (2022-12-05) ETD File Embargoed

Modern steel bridge design is moving toward the application of slender elements due to improved fabrication and construction technology. The strength and stability aspect of the liberal design philosophy has been well ...

Development of Specifications for ALDOT Mass Concrete Construction

Eiland, Andrew (2016-12-09)

In mass concrete construction, concrete temperature requirements must be established to prevent delayed ettringite formation (DEF) and thermal cracking. This involves limiting the maximum allowable concrete temperature ...

Development, Testing, and Analysis of a Rotational Friction Connection for Improving the Seismic Performance of Metal Building Systems with Hard Walls

Langley, Michael (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 ...
