Damage Detection Using Destructive Testing Of A Reinforced Concrete Slab, Michael Edward Daves
Damage Detection Using Destructive Testing Of A Reinforced Concrete Slab, Michael Edward Daves
Electronic Theses and Dissertations
Visual inspection is one of the primary tools for evaluating the health of bridges as more reach or exceed their intended lifespan. Bridge deterioration must be monitored to ensure continued safety, so owners need maintenance reports to decide on corrective actions. Strategic repair can offer asset managers the benefit of saving money and time; thus, knowing where to locate and what type of repairs can be challenging when relying on visual techniques alone. A tool designed to aid bridge inspectors is the SHE^tm program, which quantitatively measures damage location and severity for any set of time data.

Experimental Damage Diagnosis Of A Model Three-Story Spatial Frame, Samantha Sabatino
Electronic Theses and Dissertations
Structural damage can be induced by a variety of events from short-term abnormal stresses to long-term natural aging. Detection of changes in a structure's ability to withstand subsequent loads can aid decisions on safety, repair, rehabilitation, and demolition. Dynamic property shifts can show internal cracks and minor damage before propagation or failure occurs, but only if a proper indicator is selected. In order to evaluate potential damage indices, a three-story metal frame building was constructed. Using Star Modal software, dynamic structural properties were obtained from modal decomposition on experimental tap test responses. The natural frequencies and mode shapes of the …

Structural Health Monitoring With Emphasis On Computer Vision, Damage Indices, And Statistical Analysis, Ricardo Zaurin
Electronic Theses and Dissertations
Structural Health Monitoring (SHM) is the sensing and analysis of a structure to detect abnormal behavior, damage and deterioration during regular operations as well as under extreme loadings. SHM is designed to provide objective information for decision-making on safety and serviceability. This research focuses on the SHM of bridges by developing and integrating novel methods and techniques using sensor networks, computer vision, modeling for damage indices and statistical approaches. Effective use of traffic video synchronized with sensor measurements for decision-making is demonstrated. First, some of the computer vision methods and how they can be used for bridge monitoring are presented …

Investigation Of Damage Detection Methodologies For Structural Health Monitoring, Mustafa Gul
Electronic Theses and Dissertations
Structural Health Monitoring (SHM) is employed to track and evaluate damage and deterioration during regular operation as well as after extreme events for aerospace, mechanical and civil structures. A complete SHM system incorporates performance metrics, sensing, signal processing, data analysis, transmission and management for decision-making purposes. Damage detection in the context of SHM can be successful by employing a collection of robust and practical damage detection methodologies that can be used to identify, locate and quantify damage or, in general terms, changes in observable behavior. In this study, different damage detection methods are investigated for global condition assessment of structures. …
