Finite Element Simulation and Assessment of Single-Degree-of-Freedom Prediction Methodology for Insulated Concrete Sandwich Panels Subjected to Blast Loads

Newberry, Charles M. (2011-01-05)

This report discusses simulation methodologies used to analyze large deflection static and dynamic behavior of foam-insulated concrete sandwich wall panels. Both conventionally reinforced cast-on-site panels and ...

Finite Element Simulation of Precast/Prestressed Insulated Sandwich Panels Optimized for Construction of Government Facilities

Nickerson, Joseph (2014-05-02)

This report discusses the development of finite element modeling methodologies for the static and dynamic response of insulated sandwich panels to uniform pressure loads. Experimental testing, which included solid panel ...

Immediate Deflections of Simply Supported, Bonded, Class T and Class C Prestressed Concrete Beams

Hughes, Hayden (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 Vertical Ground Motion on Seismic Response of Steel Frame Structures

Wu, Hongyang (2016-02-05)

It is a well-known fact that all earthquakes have three orthogonal components of acceleration including two horizontal and one vertical acceleration. Current design practice for design of structures in United States only ...

Influence of the LRFD Bridge Design Specifications on Seismic Design in Alabama

Coulston, Paul (2011-04-01)

The Alabama Department of Transportation (ALDOT) is in the process of transitioning from the AASHTO Standard Specification for Highway Bridges to the LRFD Bridge Design Specifications. One significant difference between ...

Investigation of Pavement and Subgrade Distress at Alabama Highway 5

Stallings, Elizabeth Grace (2016-08-05)

The primary objectives of this study were to determine the root causes for subgrade failure and associated pavement distress along Alabama Highway 5 in Perry County, Alabama. In order to accomplish these goals photographic, ...

Investigation of Seismic Design of Slab-on-Girder Bridge Details in Alabama

Broderick, Joseph (2018-07-31)

The Alabama Department of Transportation (ALDOT) requested assistance to simplify and evaluate the process of designing typical slab-on-girder bridges for seismic loads. First, the determination of the seismic hazard in ...

Laboratory and Field Testing of Precast, Three Sided Arch Culverts

Meadows, Richard L. (2012-05-10)

The use of precast, three-sided arch culverts has become fairly popular for new short-span bridges and bridge replacements due to their rapid construction time, aesthetic appeal, and minimal impact to the waterway, but ...

Leveraging Automation in Data Enhancement and Quality Control Protocols for Post-Windstorm Reconnaissance Data

Rawajfih, Hadiah (2021-04-30)

Extreme windstorms cause loss of life, major financial losses, and disrupt community well-being. Post-windstorm field reconnaissance is one of the traditional methods used to collect data about these natural hazards. The ...

Low-Slip Force Friction Connections for Early Phase Energy Dissipation in Steel Structures

Koch, Patrick (2015-11-10)

Previous research suggests adding early phase energy dissipation to structural steel systems can improve seismic performance. This can be achieved with a Low-slip Force Friction (LSFF) damper designed to activate prior to ...

Numerically Modeling Structural Behavior of Precast Three-Sided Arch Bridges for Analysis and Design

Jensen, Timothy Jared (2012-05-15)

Foley Products contracted with Auburn University to perform laboratory testing and design validation of three-sided bottomless precast concrete structures being produced. Tests performed included a field test on an active ...

Seismic Response Evaluation of a Concrete Gravity Dam Considering Dam-Reservoir-Foundation Interaction

Kent, Muhammed Cagatay (2019-04-16)

The observation of the behavior of concrete gravity dams that are exposed to seismic loads is the main factor for the safety evaluation of the dams. In this regard, dam-foundation-reservoir interaction can be seen as one ...

Soil-Structure Interaction Effects on the Seismic Response of Steel Structures

Al-Ghabawi, Humam (2021-07-15)

Significant earthquakes are one of the most damaging events for structures. Much research has been done to mitigate the effect of earthquakes on structures. Soil-structure interaction can have a significant impact on the ...

Stability of Timber Bridges Subject to Scour

Schambeau, Mary (2012-07-25)

Because scour is responsible for most disastrous bridge failures, bridge scour monitoring is necessary for the safety of public roads. While much attention is paid to the amount of bridge scour at a foundation, the ...

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 ...

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 ...
