Ai-Based Bridge And Road Inspection Framework Using Drones, Hovannes Kulhandjian
Ai-Based Bridge And Road Inspection Framework Using Drones, Hovannes Kulhandjian
Mineta Transportation Institute Publications
There are over 590,000 bridges dispersed across the roadway network that stretches across the United States alone. Each bridge with a length of 20 feet or greater must be inspected at least once every 24 months, according to the Federal Highway Act (FHWA) of 1968. This research developed an artificial intelligence (AI)-based framework for bridge and road inspection using drones with multiple sensors collecting capabilities. It is not sufficient to conduct inspections of bridges and roads using cameras alone, so the research team utilized an infrared (IR) camera along with a high-resolution optical camera. In many instances, the IR camera …
Effect Of Transverse Post-Tensioning On Moment Distribution Between Channel Girders, William Eubanks
Effect Of Transverse Post-Tensioning On Moment Distribution Between Channel Girders, William Eubanks
All Theses
This thesis investigates the strength of prestressed concrete channel girders used
in bridges in South Carolina and how to improve their load distribution. The specimens
are 30 feet in length, 33 inches wide and 17 inches deep. South Carolina has 377 bridges
containing prestressed concrete channel girders and many of these bridges received a
poor load rating in a recent load rating project conducted by the South Carolina
Department of Transportation (SCDOT). The research included flexural testing of seven
individual channel girders and load distribution tests of three transversely post-tensioned
channel girders. Individual flexural testing was done to determine the …

Introduction To Infrastructure - The Influence Of Natural Disasters On Infrastructure, Tri Tam Nguyen, Sean M. Raday, Daniel Leverick
Introduction To Infrastructure - The Influence Of Natural Disasters On Infrastructure, Tri Tam Nguyen, Sean M. Raday, Daniel Leverick
STEM Student Research Symposium Posters
In this paper, three major hurricanes in 2017 were examined to determine the damage these hurricanes have done to the infrastructure. Infrastructure has an important role in the nation’s sustained economic development. Infrastructure consists of two main types which are “hard” infrastructure and “soft” infrastructure. Hard infrastructure is the physical networks which include transportation, power, etc. while soft infrastructure is institutions and human capital. Inadequate and inefficient performance of “hard” or “soft” infrastructure would prevent economy from achieving full growth. In the past decades, a significant increase in the number of natural disasters has had great impact on infrastructure systems. …
Integrated Solar Technologies With Outdoor Pedestrian Bridge Superstructure Decking, Richard K. Racz
Integrated Solar Technologies With Outdoor Pedestrian Bridge Superstructure Decking, Richard K. Racz
Masters Theses
Solar technology has been a major topic in sustainable design for many years. In the last five years, however, the solar technology industry has seen a rapid growth in installations and technological advances in cell design. Combined with a rapidly declining overall system cost, the idea of introducing solar technology into a wider range of applications is becoming a focus for engineers and scientists around the world. So many variables which alter solar energy production, such as the sun and surrounding environment, determine whether a solar design is beneficial. This thesis presents a bridge deck surface integrated with solar cells …
Underwater Explosion Energy Dissipation Near Waterborne Infrastructure, Paul R. Smith
Underwater Explosion Energy Dissipation Near Waterborne Infrastructure, Paul R. Smith
Theses and Dissertations--Civil Engineering
Underwater explosions pose a significant threat to waterborne infrastructure though destructive pressure waves that can travel significant distances through the water. However, the use of bubble screens can attenuate the peak pressure and energy flux created by explosions to safe levels. This study investigates the prediction of pressure wave characteristics based on accumulated data, the damage potential of underwater explosions based on applied loads and effective material strength, and the bubble screen parameters required to prevent damage. The results were compiled to form a procedure for the design and implementation of a bubble screen the protection of waterborne infrastructure.
The Effects Of Recycling Asphalt Use In Terms Of Economic Growth And Environmental Improvement In Kosova, Muhamet Ahmeti, Binak Beqaj
The Effects Of Recycling Asphalt Use In Terms Of Economic Growth And Environmental Improvement In Kosova, Muhamet Ahmeti, Binak Beqaj
UBT International Conference
Through this paper is analysed the possibility of recycling asphalt and reusing this in receipts of new asphalt to build road infrastructure inside urban areas and inter-urban areas, because analysing the investments that are being realized in the road infrastructure in Kosova last years, and investments that are going on, there are indicators showing economical, environmental and ….benefits of the society .
According to database of the Kosova Ministry of Transport and Telecommunication until the year 2014, the territory of Kosova has 2005.5 km of the road, 4% are highways, magisterial roads 32% and 64% regional roads, most of them …

Railway infrastructure plays a critical role in urban development, mobility, and economic growth of society. This focus issue of the Electronic Journal of Structural Engineering is devoted to a special theme, “Advances in Rail Track Infrastructure and Practice - ARTRP”. It contains articles, which were rigorously peer reviewed and accepted from a list of invited manuscripts that demonstrate significant innovation in the area of the structural engineering aspects of the rail track infrastructure. Over the past century or two, rail industry slowly but steadily evolved through significant innovations in the industry; academic research in rail is relatively new. Rail is …
Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …
Acoustic And Dynamic Characteristics Of A Complex Urban Turnout Using Fibre-Reinforced Foamed Urethane (Ffu) Bearers, Sakdirat Kaewunruen
Acoustic And Dynamic Characteristics Of A Complex Urban Turnout Using Fibre-Reinforced Foamed Urethane (Ffu) Bearers, Sakdirat Kaewunruen

A special track system used to divert a train to other directions or other tracks is generally called ‘railway turnout’. A traditional turnout system includes rails, switches, crossings (special track components), steel plates, fasteners, screw spikes, timber bearers, ballast and formation. The wheel rail contact over the crossing transfer zone has a dip-like shape and can often cause detrimental impact loads on the railway track and its components. The large impact also emits disturbing noises (either impact or ground-borne noise) to railway neighbors. In a brown-field railway track where an existing aged infrastructure requires renewal or maintenance, some physical constraints …
