8. A. Schrefler and O. C. Zienkiewicz 8alkema, Rotterdam, The Netherlands, 1988, 727 pages, £47.00, ISBN 906 191 836 7 This book consists of a collection of 91 papers presented at the International Conference on Modelling in Ocean Engineering. This conference was held in Venice in September 1988. The papers cover a broad range of topics in physical oceanography and ocean engineering. These topics have been classified by the editors into the following sections: Main lectures; Mathematical models of wind waves; Wind wave generation and wave climate; Sea level oscillations and associated currents; Transport phenomena; Fluid-structure interaction; Structural and geotechnical problems in the marinc environment. The titles of these sections provide a reasonably accurate description of the contents of this book. The stated purpose of covering such a wide range of subjects is to provide a forum for continuing dialogue and exchange of ideas between researchers working in different areas. The common link between all the papers is the use of numerical methods and computers for the predictive modelling of oceanographic phenomena and marine structures. The broad scope of this book invariably means that it contains material that will be of interest to a wide research audience. The book will be a valuable addition to libraries of research establishments. On an individual basis the book is expensive if one is interested in reading only a few selected papers. in my own area of research, compliant marine structures, ! found several papers of interest. I would recommend researchers working in other areas to at least examine the contcnts of the book. ! did discover papers which described original developments and ! believe that these papers are of significant value. However, ! must confess that I did not find all the papers that I read notable in terms of contents, clarity and presentation. There arc papers with weak sections in this book. While some of the papers are excellent in presentation, others are atrocious. This seems to be a recurrent problem with author prepared copy. I also believe that several papers would have been further enhanced by comparisons of the computer models with full-scale measurements, experiments and observations. In conclusion, this book contains a

significant amount of new material describing the use of predictive computer modelling in the fields of oceanography and ocean engineering. I would, therefore, advise researchers in these fields to familiarize themselves with the contents of this book.

L. J. Morris and D. R. Plum Longman Group (UK) Ltd, 1988, 280 pages, £ 13.95, ISBN 582 02 3572 This student textbook is divided into two parts. The first, consisting of 10 chapters, deals with the design of structural steel elements to BS 5950. The coverage is extensive and includes beams, purlins, crane girdcrs (excluding plate girders), trusses, columns, connections and bracing. A chapter is also devoted to comIx)site construction. The purpose of this section of the book is to set out in detail the design of individual structural elements. In so doing the application of code clauses is clearly explained but little background information on the reasons behind the recommendations is presented. An interesting and useful feature of this part of the book is the realistic examples selected to illustrate the design procedures. The examples give a complete solution, including determination of loading and selection of suitable members. Academic examples, "Show that the beam in figure I is capable of supporting...", have been avoided. The second part of the book presents worked examples of the design of three complete structures--a single storey building of lattice girder and column construction, a portal frame and an office block featuring composite construction. The aim of this second part is to illustrate how individual members may be combined to form a complete structure. Particular attention is paid to loading and structural response and, importantly, overall stability. The examples chosen are well illustrated and fully explained. For this reason this second part of the book widens its appeal from its intended audience to practising engineers who are approaching the design of one of the above structures either for the first time or are as yet unfamiliar with their design using the limit-state steelwork code BS 5950.

Throughout the book the authors explain the design procedure, from initial client briefing to production of fabrication drawings and inspection of steelwork. This should be of particular interest and value to students, since many fail to appreciate the significance of decisions made at the design stage. Example calculations are clearly presented in a logical sequence, providing good models for students to follow in practice. As a student textbook, StructuralSteelwork Design to BS 5950 has much to commend it. I think it will be appreciated most by students who have already grasped the basics of elemental design and now wish to proceed to design complete strutures. Part ! of the book will then serve as a reference text for details of individual member design. Practising engineers with little experience of design with the new code would, I am sure, find much useful information in the book, too. The authors have produced a very readable, practical and informative book.

Steel beam-column connections


W. F. Chen (ed) Elsevier Appl/ed Science, Barking, UK, 1988, 482 pages, £75.00, ISBN 1851 66 22 51 This book contains a collection of 13 separate papers which were originally published in the Journal of Constructional Steel Research. The editor's objective is to draw together the knowledge of key researchers from different parts of the world in order to provide a state-of-the-art summary of recent experimental studies undertaken to provide an understanding of the behaviour, analysis and design of steel beam to column connections and their influence on the behaviour of frames. After an introductory paper concerned largely with the history of the design of structural steelwork, the book is divided into three sections of four papers each. The first section is concerned with connections as structural elements and describes the design considerations in the diffcrent types of beam to column connections. Thc authors of these chapters have given detailed consideration of stiffness and ductility as well as strength. The second section describes various aspects of the influence of connection behaviour on the performance of columns and complete frames. The final section is conccrned with the design rules currently in
