Implosion of steel fibre reinforced concrete cylinders under hydrostatic pressure

grantor: University of TorontoThis thesis describes an experimental tea program and subsequent analysis devoted to the study of steel fibre reinforced concrete cylinders which implode under hydrostatic water pressure. The cylinders model components of gravity base structures beneath oil and gas platforms in the North Sea. Five cylinders were tested in the Hydraulic Test Facility at the University of Toronto. They had an outer diameter of 610mm, and a thickness of 19mm. The Length-to-outer-diameter ratio varied from 1.0 to 2.5. The total volume of fibre reinforcement was either 1% or 6% of the concrete volume. The cylinders are analyzed using a method developed by Haynes and Nordby, using Olsen's Method which is a popular design method, and finally using RASP ®, a reinforced concrete shell finite element program developed at the University of Toronto. The results of the analyses are compared to experimental results.M.A.Sc
