Non-Destructive Means Of Predicting Masonry Prism Strength Using Ultrasonic Pulse Velocity (Upv), Connor J. Barlow
Non-Destructive Means Of Predicting Masonry Prism Strength Using Ultrasonic Pulse Velocity (Upv), Connor J. Barlow
UNLV Theses, Dissertations, Professional Papers, and Capstones
Current ASTM standards call for grouted masonry prisms to be tested for compressive strength at 28-days to ensure compliance with the structural design. In the event of failing tests, the subject samples may require redesign or reconstruction which can pose problems due to ongoing development around and including the prisms between the time of placement and obtaining test results. The purpose of this research is to determine if the use of ultrasonic pulse velocity (UPV) testing can be utilized to determine a correlation between prism composite strength of the masonry prism with ultrasound readings as to provide preliminary means of …
Three-Dimensional Finite Element Numerical Analysis Of Closely Spaced Foundations Resting On Clay Soil Supported With A Geocell Mattress Embedded In A Fly Ash Layer, Yahia Iskander
UNLV Theses, Dissertations, Professional Papers, and Capstones
This dissertation studied several models supported by a geocell mattress filled with fly ash material as a filling material on top of a clay soil bed. Two square rigid steel plates presenting footings with different spacing between them were subjected to loading. The effect of spacing between footings on the function of the system was investigated by measuring the footings load and settlement.In the past, limited cases were studied for closely spaced footings. The subject of two closely spaced footings on clay soil supported by geocell has not been researched before. Most of the previous research was on sandy soil; …
