Exploitation of oil and gas reserves from hydrocarbon reservoirs below the sea bed has increased rapidly since the 1960s. However, the wide range of subject areas within ocean engineering has posed problems in the teaching of students because it involves reference to textbooks on many disciplines including corrosion metallurgy, meteorology, process engineering and even marine biology. In this textbook, the author aims to present an integrated treatment of the main subject areas which contribute to the design, construction, installation and operation of fixed and floating offshore structures. It emphasizes the fundamentals of oceanography, fluid mechanics, wave theory, hydrodynamics and structural analysis. Sections on model testing, full-scale measurements, design and certification are also included to ensure that the book is of value to professional engineers.

Author: C. A. Brebbia, Stephen Walker | Size: 4 MB | Format:PDF | Quality:Scanner | Publisher: Newnes-Butterworths | Year: 1979 | Pages: 323 | ISBN: 0408003936, 9780408003933
The discovery of large deposits of oil and gas in deep-water regions has resulted in the construction of large production and drilling platforms, which often have to withstand severe environmental conditions in inhospitable areas. Often the natural period of vibration of these structures is comparable with the typical period of variation of the environmental forces, making a dynamic spectral analysis necessary.
This book starts by explaining the fundamentals of probabilistic processes, develops the theory necessary for the description and analysis of sea states and describes the random-vibration approach to structural response.
Chapter 3 explains the essential hydrodynamics of water waves, describes wave forecasting, and defines the statistical parameters associated with sea state description.
Chapter 4 deals with the calculation of wave forces on slender members (such as those used in the construction of steel lattice-type structures) using Morison's equation.
Chapter 5 describes extensively the use of diffraction theory in the calculation of wave forces on large-diameter bodies such as those found on concrete gravity-type structures.
In Chapter 6, the study of environmental forces is completed by describing the effect of currents and winds.
Chapter 7 is an introduction to the theory of vibration, including a description of the spectral approach.
Chapter 8 describes the extension of this theory to multi-degree-of-freedom structures, as well as giving a brief introduction to the method of matrix analysis of structural response.
Finally, in Chapter 9 some case studies are reported, and the problems of fatigue and soil-structure interaction are discussed.

First published in 1967, Professor Batchelor's classic text on fluid dynamics is still one of the foremost texts in the subject. The careful presentation of the underlying theories of fluids is still timely and applicable, even in these days of almost limitless computer power. This re-issue should ensure that a new generation of graduate students see the elegance of Professor Batchelor's presentation.

With GIS technologies ranging from Google Maps and Google Earth to the use of smart phones and in-car navigation systems, spatial knowledge is often acquired and communicated through geographic information technologies. This monograph describes the interplay between spatial cognition research and use of spatial interfaces. It begins by reviewing what is known about how humans process spatial concepts and then moves on to discuss how interfaces can be improved to take advantage to those capabilities. Special attention is given to a variety of innovative geographical platforms that provide users with an intuitive understanding and support the further acquisition of spatial knowledge. The monograph concludes with a discussion of the number of outstanding issues, including the changing nature of maps as the primary spatial interface, concerns about privacy for spatial information, and a look at the future of user-centered spatial information systems.

Abstract
The problem of the progressive collapse of a building has been addressed using a reinforced concrete
flat slab frame. This structure was tested in the past at the ELSA laboratory to evaluate safety margins
against collapse. Static linear and nonlinear analyses of the building under column removals had first
been performed and then, in the experiment, columns had been successively removed, slowly
demolished with a crunching machine. The experiment showed that the structure survived the
demolition of two central columns, and also that structural testing against progressive collapse can be
very challenging.
Extending the scope, the dynamic nature of the loading has been considered in this report since
buildings can be exposed to fast dynamic abnormal events, such as explosions or impacts, which may
destroy abruptly load bearing elements. Thus, this study tries to answer the question of what would
have happened to this building if the columns had been destroyed dynamically. For the same
structural model dynamic linear and nonlinear analyses have been performed employing the finite
element computational framework of the SAP2000 code. Alternately, three columns, a central and two
corner ones, have been instantaneously removed and the structural response of the frame calculated.
Maximum values of bending moments and forces at critical sections are reported and compared to
those of the static analyses. Time histories of deflections of nodes above missing columns are
determined, and several ratios of response parameters resulting from the different analyses are
produced for comparison purposes. All approaches predict no mechanism which might lead to
progressive collapse, even though several hinges are formed. Advantages of the use of static or
dynamic, linear or nonlinear analyses are discussed.
