3. Application of the above methods of analysis to special topics such as stability, shell theory and suspension bridges. There is, in addition, a very useful chapter in which the basic stress definitions are given and the stress-strain relationships outlined. The number of topics covered would appear to be very large for a single volume containing 442 pages but the authors have, by their style of presentation, overcome this difficulty. Descriptions, although adequate, have been reduced to a minimum and the arguments clarified by the use of examples. In addition, exercises with answers are provided at the end of each chapter, and the authors have anticipated the change to metric units by using SI units throughout. This is a textbook which I would have no hesitation in recommending to undergraduate students.
FOR A N U M B E R of years the methods of solution of structural problems have been undergoing a change. Previously solutions were obtained using a direct application of energy principles or an approximate numerical approach but now these methods are being replaced by newer ideas which rely on a matrix formulation of the problem. A large number of textbooks have been published describing the application of the older methods and quite a number are now appearing which illustrate the use of matrix methods, but in this book by Marshall and Nelson both methods of analysis are introduced. The authors have succeeded in their aim of presenting a work suitable for undergraduates at all stages of their course, and also an introduction for older engineers to the new methods of analysis. The subject matter treated can be conveniently divided into three sections. 1. The solution of determinate and indeterminate beams, trusses and frames using strain energy, moment distribution and model methods of analysis. 2. An introduction to the solution of statically indeterminate structures using both the stiffness and flexibility matrix approach.

Building on Springs R. A. W A L L E R Series of Monographs in Civil Engineering. Vol. 2, 88 pp., 37s. 6d. Pergamon, Oxford, 1969.
A VARIETY of factors has led to the need for vibrations in buildings to be considered more seriously than in the past. One of these factors is the need to build in close proximity to a major source of vibration such as an underground railway. This book comprises a practical review of methods available for isolating buildings from ground-borne vibration of this kind by mounting them on springs. Basic principles are first discussed followed by consideration of the properties of various types of
springs and their detailed design. Examples of buildings are quoted and there is reference to costs and benefits. The treatment is thoroughly practical and although brief is supported by references at the end of each chapter. The book is certainly timely and can be confidently recommended to building designers as an introduction to this new branch of technology. A. W. HENDRY 123
