Evaluation of the Rapid Rutting Test and High Temperature Indirect Tensile Test for practical use in asphalt mix design, quality assurance, and quality control
(University of Missouri--Columbia, 2023)
The asphalt industry has a large number of mixture performance tests available to evaluate a mix design's ability to withstand typical pavement distresses. Some of these tests are widely used whereas others tend to fall ...
Risk-based life expectancy of highway guard cables
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/1/2024] Starting in the mid-late 2000's, Missouri began phasing out low-tension cable barriers in favor of proprietary high-tension cable systems due to the improved safety characteristics of high-tension ...
A comparative study between solid, porous, and equivalent homogenous truss structures with embedded metamaterials
(University of Missouri--Columbia, 2023)
Metamaterials are a class of engineered materials with various microstructures that can achieve properties unattainable with conventional materials. For instance, inspired by natural materials such as bees' honeycombs and ...
Full-scale glass curtain wall systems under quasi-static loading
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/1/2024] Extreme events such as blasts can cause severe damage to the structural integrity of the building. Today, glass curtain wall (CW) systems are very popular facade solutions for government, ...
Experimental study of cold formed steel roof truss connections
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] Cold-formed steel (CFS) roof trusses are commonly used due to their cost effectiveness, reliability, and high stiffness to weight ratio. To increase the effectiveness of these widely used trusses, ...
Evaluation of an autonomous truck mounted attenuator system in work zones
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] Improving work zone safety is a priority for state and local transportation agencies. Mobile and slow-moving operations experience another threat in the form of errant vehicles crashing into the ...
A phase-field formulation for fracture modeling of quasi-brittle and rate- and temperature-dependent materials
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] This thesis focuses on the development and application of the phase-field method for fracture modeling of brittle, quasi-brittle, and viscoelastic materials. The study begins with a comprehensive ...
Edge computing - enabled road condition monitoring : system development and evaluation
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] Real-time pavement condition monitoring provides highway agencies with timely and accurate information that could form the basis of pavement maintenance and rehabilitation policies. Existing ...
Blast response of structural envelope elements : LG windows and CFS roof trusses
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2025] Building safety continues to be a concern due to the increasing number of explosion threats targeting civilian and government buildings. Building envelope elements, such as walls, windows, and ...
GIS-based analysis of environmental justice and compound natural hazards in the built and natural environment
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] Infrastructure design connects people and the built environment with the natural world; thus, accessible, equitable, and sustainable infrastructure is critical for community resilience. As changing ...
Multi-headed self-attention mechanism-based Transformer model for predicting bus travel times across multiple bus routes using heterogeneous datasets
(University of Missouri--Columbia, 2023)
Bus transit is a crucial component of transportation networks, especially in urban areas. Bus agencies must enhance the quality of their real-time bus travel information service to serve their passengers better and attract ...
Characteristics of mean flow and turbulence in bubble plumes
(University of Missouri--Columbia, 2023)
Bubble plumes are phenomenon when bubbles enter water continually and move through the water column, which is widely seen in both natural environment and industry. This dissertation investigates bubble plumes from different ...
