There are many books available which explain structural theory and allow the question, Why is it done? to be answered. However, it does appear that there is a need to produce a book which illustrates how the available information is used to produce a structurally sound solution. It is hoped that this publication will go some way in meeting that need. The design calculations have been done by hand on calculation sheets with the aim of exposing the student to normal office practice. These sheets have, in the left-hand margin, referred to the various clauses of the British Standards. It is expected that the student will have available either the full standards or the publication Extracts from British Standards for Students of Structural Design. From the above it is obvious that for the successful completion of any structural design there must be the marriage of theory and practice. This book really deals only with the latter, thus its readers are expected to have some competence in the theoretical behaviour of structures. The book should not be used therefore as a layman's guide to structural design. Those who will benefit most from the text are technician and undergraduate students of civil and structural engineering, building and architecture. It may also prove beneficial in updating practising engineers. Computer aided design has been excluded from this book, mainly because there is such a proliferation of software available that it is totally unnecessary for students to write their own programmes.
