Download or read book Failure of Thick walled Concrete Spheres Subjected to Hydrostatic Loading written by H. H. Haynes and published by . This book was released on 1970 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two modes of failure for hollow concrete spheres subjected to hydrostatic pressure loadings are discussed, and the experimental results are presented. The first mode of failure was crack development in the plane of the concrete wall, and the second mode was implosion. From experiments using 16-inch-OD spheres, the difference between the pressures at failure for the two modes ranged from 0 to 50%. Expressions to predict the pressures at initiation of in-plane cracking of the concrete wall and the pressures at implosion are presented. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Nine model concrete spheres reinforced with steel liners located on the inside, outside, or both inside and outside were tested to failure under hydrostatic loading. The quantity of reinforcement varied from 1.8 to 23.9% by area; for this range of reinforcement, the spheres showed increases in failure pressure from 0 to 374% over that of unreinforced concrete spheres (2,810 psi). Using a nominal 12% reinforcement, it was found that the best reinforcing method was to place liners on both the inside and outside of the wall. (Author).

Book excerpt: At the FIP Symposiu m on Concrete Sea Structures, which was held on 28-29 September 1 972 in Tbilisi, Georgia, the participants unanimously agreed that c oncrete was bound to play a major if not the leading part in the rapidly developing field of offshore construction. It was also agreed that the discovery of oil and gas in the North Sea had produced an immediate and exciting challenge in the demand for the construction of fixed structures in marine environments which, in terms of hostile natura! forces, would far exceed anything tackled by engineers to date. It was therefore decided to set up an FIP Commission on Concrete Sea Structures under the chairmanship of Mr Fr,óde Hansen which would report to the FIP Seventh Congress in New York in May 1974 . It seemed natura! to divide the tasks of the Commission into three working groups: Design, Materials, and Construction Methods. It soon became apparent that the demands for structures subjected to deep and hostile waters were so great and so pressing that it was decided to accelerate the work of the Design and Materials Working Groups, and to produce the first edition of these Recommendations before the New York Congres s . The Chairmen for the two Working Groups were Mr Kurt Eriksson and Dr Odd Gjprv respectively. The publication of these Recommendations has been made possible by the li vely interest of these two groups and by the valuable assistance of Mr D. Palmer and Mr B. Spratt of the C ement and Concrete Association and Mr M. D. Hazen of Sir Robert McAlpine & Sons Ltd. The Recommendations have been published with the approval of the FIP Administrati ve Council. The work of the Construction Methods Working Group has not been included in this edition since practical construction experience in this most challenging field is still quite limited. The successful completion of the Ekofisk Storage Tank has added tremendously to obtaining practical experience, and this, with the fact that two larger concrete offshore platforms will soon be under c onstruction, offers the promise that future editions will be augmented by some very valuable practical construction experience.

Download or read book Behavior of Steel Bar Reinforced Concrete Spheres Under Hydrostatic Loading written by N. D. Albertsen and published by . This book was released on 1975 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four reinforced and two unreinforced concrete spheres of 32.00-inch outside diameter (OD) and 2.71-inch wall thickness (t) were tested under hydrostatic loading to determine the effect of embedded steel reinforcement on structural behavior. Test results show that the reinforced spheres (0.44 or 1.10% steel by area) failed by implosion at values for the ratio of implosion pressure to concrete strength that were on the average 5% lower than for the unreinforced spheres of the same size. In addition, the reinforced spheres developed cracks in-the-plane-of-the-wall at the inner surface of the reinforcement cage prior to implosion. Implosion results for the unreinforced spheres are 10% lower than predicted by an empirical equation developed from previous tests of unreinforced 16-inch OD spheres. These results provide initial insight into the behavior of hydrostatically loaded steel bar reinforced concrete spheres and indicate that additional test data is required before definitive design guides can be developed.
