This book aims to provide a comprehensive understanding of the design and construction of water-retaining structures, allowing graduate civil and structural engineering students, as well as the practising engineer, to build with speed and economy. Assuming some familiarity with BS 8110 "Structural Use of Concrete" the book draws on examples, many of which are based on actual completed structures, and upon extensive tables, related to the analysis of rectangular, circular and conical structures, to develop good working practice. The tables and examples should enable the engineer to check, by hand, the often complex results of computer analysis and output, usually based on the finite element method, for most structures. This is particularly so in those cases where the forces within a structure are affected by the ground upon which they sit. Thus, methods of design for the soil/structure interaction, which normally require the aid of complex computer programmes, are included. The tables and examples provide regulations, and should give direction to the student engineer in the use of current British Standards for the design of many types of concrete structures. An essential part of the book are the listed computer programmes and output which further assist the designer in obtaining a range of options from which the most effective and economical solution may be determined for a particular structure. Whilst a useful appendix covers the analysis of ground-supported open circular concrete tanks.
