Compressive Behavior Of Masonry Columns Confined With Steel Reinforced Grout (Srg) Composite, Sarah Elizabeth Jemison
Compressive Behavior Of Masonry Columns Confined With Steel Reinforced Grout (Srg) Composite, Sarah Elizabeth Jemison
Masters Theses
"In this study, a new type of composite comprised of steel fiber cords embedded in a natural hydraulic lime mortar matrix, known as steel reinforced grout (SRG), is explored for the use in confinement of masonry columns. An experimental study was carried out to understand the behavior of solid clay brick masonry columns confined by SRG jackets. Twenty-four confined and seven unconfined columns with a square cross-section were tested to failure under a monotonic concentric compressive load. Test parameters considered were the column corner condition, number of fiber jacket layers, and number of fiber overlapping faces. SRG confinement improved the …

Damage Detection Through Acoustic Emission Of Fracture Processes In Concrete Masonry Units, John Alexander Cain
Masters Theses
"Masonry structures are vulnerable to earthquakes; their brittleness and discontinuous formation make them susceptible to collapse. In the event of an emergency, this could be detrimental and perhaps fatal. The area of Structural Health Monitoring (SHM) is focused on understanding the behavior of structures for the sake of safety and predicting their longevity. One applicable technique to monitor this behavior is Acoustic Emission (AE). Acoustic Emissions are transient elastic waves released as microcracks nucleate from stress intensities, coalesce into cracks and then accumulate as damage. AE monitoring is a favorable method because it is capable of detecting cracking from within …
