Sensor characterization for long-term remote monitoring of bridge piers
(University of Missouri--Columbia, 2007)
Structural instability of bridge piers resulting from scour or other natural hazards can lead to bridge collapse. A monitoring system that analyzes bridge pier behavior could prevent this type of failure by detecting ...
Condition assessment of Kevlar composite materials using Raman spectroscopy
(University of Missouri--Columbia, 2007)
This thesis presents the results of an investigation of the Raman scattering effects of aging Kevlar composite strands. The goal of this research is to investigate the potential application of Raman spectroscopy as a ...
Environmental effects on subsurface defect detection in concrete structures using infrared thermography
(University of Missouri--Columbia, 2009)
Deterioration of concrete due to corrosion of embedded steel reinforcing bars and prestressing strands represent a significant challenge for inspection and maintenance engineers. Cracking, delaminations and spalling that ...
Optimization of electromagnetic acoustic transducers for nondestructive evaluation of concrete structures
(University of Missouri--Columbia, 2008)
There are more than 130,000 prestressed concrete bridges in the United States with about 37,000 bridges being more than 30 years old. Prestressing steel strands are an important construction element used in these bridges ...
Long-term sensing system for bridge piers
(University of Missouri--Columbia, 2009)
Structural instability of bridge piers resulting from scour or other natural hazards can lead to bridge collapse. As a result, a method of monitoring bridge piers is needed to evaluate long-term changes in structural ...
Guideline for implementing quality control and quality assurance for bridge inspection
(University of Missouri--Columbia, 2009)
Structurally deficient bridges are becoming more and more prevalent. The need to identify and correct these deficiencies is becoming increasingly apparent. This task is assigned to bridge inspections. With such a critical ...
Remote health monitoring for asset management
(University of Missouri--Columbia, 2009)
This project explored the development of real-time monitoring technology to be used for effective asset management. There is a critical need to develop technologies to assess and monitor the condition of these bridges over ...
Condition assessment of carbon fiber composites using raman spectroscopy
(University of Missouri--Columbia, 2009)
The goal of this research is to examine the potential of Raman spectroscopy as a method of condition assessment for carbon fiber composite materials. Carbon fiber composites are used in high performance situations such as ...
