Static and dynamic analyses of plates and shells: theory, software and applications
B O O K REVIEWS Frame and slab structures G.S.T. Armer and D.B. Moore (eds) Butterworths, London 1989' 304 pages, £35.00, ISBN 40803669 9 The proceedings of a conference/ seminar held in 1988 in memory of Dr Randal H. Wood form the basis of this book. As the tide indicates, the main thrusts of the book are in the areas of frame analysis, connection behaviour, lightweight cladding, composite action, and plastic design of concrete slabs. The common thread to this seemingly disparate group of subjects is Dr Wood's interest in them and contribution towards the present state of knowledge. The book contains twelve chapters; two of which are papers of Wood's published in the 1950s, one a list of Wood's publisltad works, and nine on the topics listed above and written by a collection of well-known experts. Even today, some 30 or more years on, Wood' s two papers would be comidered essential reading for students of the subjects--stability of buildings and composite action of walls and supporting beams, The ~ from the other authors are a combinatiou of state-ofthe-art reviews and more detailed descriptions of recent developments with which the particular author has been involved The style of the ~ varies enor moulsy, not so much because of the different writers, but because of the nature of the subjects which range from the very theoretical, for example 'Hillerborg's advanced strip method', to the descriptive, like 'New developments in composite coummmiou' However, in most cases coatributon have reflected Wood's aim to be practical and to link theoretical d e v ~ to design

engineers, as well as academics, should find vah~ in this book Despite the nmniPJ of matdlmmrs the editors have ~ that the appearance is uniform (except for Wood's papers). Its 143 dingrams and 22 ldmtogfaphs are clear and follow a similar format throughout the book. The paper quality of the 304 ~ and the hardcover binding are reflected in the fairly high price of £35.00. Altogether it is a unique book which would enhance the shelves of any senior design engineer, academic or technical library.

Static and dynamic analyses of platOS and shells: theory, softwm
and apldications
Hou-Cheng Huang Springer Verlag GmbH & Co KG, FRG, 1989, 194 pages, DM 295.00, ISBN 354019538 6 This book follows the thrust of Hinton and Owen's software series books, such as books entitled Finite Element Programming. The book deals with software development for MindlinReissner type plate and shell finite element solutions; in fact, the listed programs in the book are based on the available programs in the Hinton and Owen's series books, except that the author has improved some of the early developments. There are nine" chapters and two appendixes containing the software description for elasto-plastic static and transient dynamic analysis, respectively. As a unique feature of this book, two IBM and one Apple Mac floppy discs are included to provide the users with the source code of the programs and test examples. However, exercise problems are not provided within the individual chapters. The first chapter contains a short introduction which briefly describes the changing trends in shell analysis, reliability of finite element analysis in general and shell finite element analysis in particular, three types of possible shell element formulations, and the objective/scope of the entire book. Chapter two presents the degeneration of 3-D continuum theory to MindlinReissner type plate and shell theory. This chapter covers also the thin plate theory based on the Kirchhoff hypothesis. The most popular plate and shell element formulations, which are based on Mindlin- Reissner theory, are described in chapter three, along with the associated undesirable phenomena called locking and spurious singular modes. Strategies to improve the performance of the Mindlin-Reissner type plate and shell elements are discussed in chapters four and six respectively. Linear benchmark tests are given in chapters five and seven for plate and shell problems, respectively. Finally, chapters eight and nine extend, formulate and apply the MindlinReissner plate and shell elements for elasto-plastic static and transient dynamic analysis, respectively. The author tries to present the state-
of-the-art of the development of plate and shell elements. But, at the same time, he also points out the consensus among leading researchers that there is no such thing as a 'defect free' shell element. There are still possibilities for misuse in analysis. Even though much about the behaviour of shell element is known, trying to isolate the characteristics of the ideal shell element is rather like attempting to hit a moving object. Anyway, the book is a very valuable contribution for research students/ workers, and engineers in universities, industry, etc., who use shell elements in their projects.

Innovative apldiemimm of shells and spatial fomw, volumes I, II and I!1 A.A. Balkema, The Netherlands, 1989, 1600 pages, £107.00, ISBN 906191940 I Each year the International Association for Shell and Spatial Structures (lASS) organizes an imematiouaJ symposium in different parts of the world. In 1988 the symposium took place during 21-25 November in Bangulore, India, under the conference theme 'Innovative Applications of Shells and Spatial Forms'. One hundred and eight papers by engineers, architects, contractors and research groups from 25 countries are published within three volumes. The large spectrum of the conference theme requires adequate classification. This has been achieved by dividing the whole conference into 13 sections. Thirteen different chapters cover the wide range of shells'and spatial forms. The different papers deal with architectural aspects, with forms and materials, with linear and nonlinear structural analysis including dynamics, vibration, stability and buckling problems and structural design. Further chapters cover different structures like space forms, tension structures, shell foundations, cooling towers and ferrocement shells. Papers concerning experimental investigations and construction aspects complete the varaiety of innovative applications of shells and spatial forms.
