In recent years both free-standing and geometric staircases have become quite popular. Many variations exist, such as spiral, helical, and elliptical staircases, and combinations of these. A number of researchers have come forward with different concepts in the fields of analytical and numerical design and of experimental methods and assessments. The aim of this book is to cover all these methods and to present them with greater simplicity to practising engineers.

Staircases is divided into five chapters: Specifications and basic data on staircases; Structural analysis of staircases – Classical methods; Structural analysis of staircases – Modern methods; Staircases and their analysis – A comparative study; Design analysis and structural detailing. Charts and graphs are included and numerous design examples are given of freestanding and other geometric staircases and of their elements and components. These examples are related to the case studies which were based on staircases that have already been constructed. All examples are checked using various Eurocodes.

The book includes bibliographical references and is supported by two appendices, which will be of particular interest to those practising engineers who wish to make a comparative study of the different practices and code requirements used by various countries; detailed drawings are included from the USA, Britain, Europe and Asia. Staircases will serve as a useful text for teachers preparing design syllabi for undergraduate and post graduate courses. Each major section contains a full explanation which allows the book to be used by students and practising engineers, particularly those facing the formidable task of having to design/ detail complicated staircases with unusual boundary conditions. Contractors will also find this book useful in the preparation of construction drawings and manufacturers will be interested in the guidance given in the text.

High strength fibre composites (FRPs) have been used with civil structures since the 1980s, mostly in the repair, strengthening and retrofitting of concrete structures. This has attracted considerable research, and the industry has expanded exponentially in the last decade. Design guidelines have been developed by professional organizations in a number of countries including USA, Japan, Europe and China, but until now designers have had no publication which provides practical guidance or accessible coverage of the fundamentals. This book fills this void. It deals with the fundamentals of composites, and basic design principles, and provides step-by-step guidelines for design. Its main theme is the repair and retrofit of un-reinforced, reinforced and prestressed concrete structures using carbon, glass and other high strength fibre composites. In the case of beams, the focus is on their strengthening for flexure and shear or their stiffening. The main interest with columns is the improvement of their ductility; and both strengthening and ductility improvement of un-reinforced structures are covered. Methods for evaluating the strengthened structures are presented. Step by step procedures are set out, including flow charts, for the various structural components, and design examples and practice problems are used to illustrate. As infrastructure ages worldwide, and its demolition and replacement becomes less of an option, the need for repair and retrofit of existing facilities will increase. Besides its audience of design professionals, this book suits graduate and advanced undergraduate students.
