Buckling of offshore structures

Buckling of Offshore Structures, by J.P. Kenny and Partners Ltd. (C.P. Ellinas, W.J. Supple and A.C. Walker), Granada, London, 1984. ISBN 0-246-12298-6, xxxvii + 472 pages, illustrated,hard-cover, £40. This major new book presents detailed critical comments on the design of a wide range of structural components and on types of loading related to the buckling of offshore structures. The preface of the book mentions that the Department of Energy of the United Kingdom recognised a need to provide critical comments to engineers using the various Codes/Design Rules, in order that the limits of validity and degree of safety of the various recommendations contained in the codes were clearly identified, and that any dispamties or causes of misunderstanding between various codes were clarified. To this end, the Department of Energy initiated a study with J.P. Kenny and Partners Ltd. of London at the beginning of 1982, one of the objectives of which was to collect and collate on a common basis all the available test data on the buckling of these structural elements. The experimental database thus formed could then be used to assess the validity and safety of existing Design Codes and the value of new theoretical developments. During the course of this Department of Energy study the J.P. Kenny project team contacted the vast majority of internationally recognised experts in the field of structural buckling, requesting them to send the most up-to-date information and experimental buckling data in their possession, so that this could be evaluated and included in the study. The Department of Energy also set up a Buckling Review Panel to examine the output from the study and to advise the Department on all aspects relevant to the study. The volume is divided into five major parts, which culminated from different phases of the project, each part containing numerous chapters. The various parts are on: Ring-Stiffened Cylinders; Stringer-Stiffened and Orthogonally-Stiffened Cylinders; Flat Panels; End Closures and Transition Shells. In addition, the book contains definitions of special terms, abbreviations, lists of codes, rules and guides. Another asset of this work is the exhaustive list of references provided at the end of each part. It is well established that an increasingly important aspect in the design of steel offshore structures is the buckling behaviour of their constituent structural elements. These include bracing members, stiffened and unstiffened cylinders, end closures and orthogonally stiffened plating. A substantial body of information exists relating to these structural elements which includes both theoretical and experimental results. The information in the book has, however, been arranged in such a manner that it can be helpful to designers in a number of ways. In the first of these, the comparisons between the Code predictions and the experimental results can indicate the degree of reliance which engineers may place on the predictions. Another manner in which the information in this book can be used is in the
387 case where progressive developments in structural form may result in a requirement for design data outside the range presently available. This book presents a genuine state-of-the-art of the knowledge in the field of buckling behaviour of offshore structures. At only £40, it is without doubt inexpensive, considering the amount of information presented by well-known experts. Finally, the reviewer must mention that, albeit its title implies that the book provides information on buckling of offshore structures, it should be equally useful for assessing the structural integrity of any lattice booms, platforms, panels, dishes, and general shells.

Engineering Mechanics, by D.K. Amand and P.F. Cunniff, AUyn and Bacon, London, 1984. Statics, ISBN 0-205-07784-6, xvi + 329 pages, hard-cover, £12.95. Dynamics, ISBN 0-205-07785-4, xvii + 281 pages, hard-cover, £12.95. This is a two-volume set, where the presentation of the topics is based on the authors' classroom experience. The subject matter in both of the volumes has been arranged in such a manner that engineering students can follow it with ease. Numerous worked-out examples are included, with clear diagrams and explanations. A useful additional feature is the summary of the important ideas and the equations that have been provided at the end of each chapter. Examples and assigned problems incorporate both the S.I. and the English system of units. In their preface the authors summarise the purpose and philosophy of these books excellently, the description below providing the reader with their views.
Statics Chapter 1 reviews the subject of vectors and the fundamental laws useful for the study of statics. The concepts of force and couple are introduced in Chapter 2, where we also consider the equilibrium of a particle. The equilibrium of rigid bodies is then covered in Chapter 3. Although two- as well as three-dimensional equilibrium is considered, stress is placed on the former since the salient points can be grasped without introducing algebraic complexity. The equilibrium of structures and frames is presented in Chapter 4, where the graphical approach has been adopted in light of current developments in computer graphics. Centroids and distributed loads are considered in Chapter 5, which also includes the analysis of the cable. Following-up on the concept of the first moment, the area moment of inertia and the mass moment of inertia are introduced in Chapter 6. Here the authors have deliberately avoided a lengthy treatment of three-dimensional integrating procedures. Area and
